I was using one of the old Firefox ESR versions (can't remember exactly which) because I was still on an old Mac OS version, 10.9 to be more specific.

I recently updated to macOS Sierra 10.12.6 and as a result, as soon as I opened Firefox, I went to check if it would update on its own and it did. It updated to version 91.6.0 esr. After this update, something weird happened: the browser won't load any page.

I checked, it's not an internet connection, because other browsers are working normally. It won't load any extensions either. So I want to fix this issue with an update.

The question is this: I remember installing what was called Firefox Quantum. As of now, the name on the about section is just Firefox Browser, maybe because of the updates. • Can I install the latest "regular" Firefox 97.0 on top of the this old installation, just using a standalone dmg file? • Will this installation preserve everything that's already in the browser? By everything I mean bookmarks, extensions, history, cookies, etc.

It seems to me that the automatic updater isn't installing version 97.0 on its own because it's coming from the ESR versions. So it's stopped at 91.6.0 esr.

Thanks in advance

Hi All! Need some help for a client please :) iMac 27in (late 2013) Processor = 3.2Ghz Quad Core Intel Core i5 Memory = 8GB DDR3 MacOS Catalina = 10.15.7 1TB HDD Not sure if this is a MacOS thing or a Firefox thing. My client would prefer to use Firefox, currently using Chrome. However - whenever they close Chrome or shutdown / restart the computer, Firefox looses everything and they have to re-import all the data from Chrome. This is happening on a continual basis. It's simply not saving any data / settings that are imported from Chrome.

Thanks!

FIX what seem to be CLEAR conflicts with relationship between platform and user's device (desktop, Dell Optiplex 790 in my case - that do NOT occur with Opera, otherwise) as WELL as aforementioned ATROCIOUS performance quality - BTW, this is the SECOND update / upgrade I've done in LESS than a WEEK.....

Hi there,

My firefox was lagging so much that I opted to uninstall and then reinstall it. Unfortunately, the version that is available wouldn't work with my old version of Mac. It is OS.10.11.6 Is there an older version of firefox that I can use it with (or even restore?)

Many thanks in advance for your assistance.

Hi there, I've downloaded Firefox but I only seem to have the disc image, how to I get the app to open? It's in my applications file. I have a MacBook Pro with High Sierra version 10.13.6 OS. Many thanks in advance. Best regards, Anna Daley

(SECOND occurrence of this problem; not sure HOW previous instance resolved - my short-term memory ISN'T the best at present!)

Have taken all recommended steps short of completely refreshing (renamed a file titled 'config.json.old' as it was the ONLY one with a 'json' filepath suffix) because I don't want to have to relocate (another) existing session / configured profile by trial & error if avoidable - 'cookies' were removed along with history / cache cleared; reset / deleted related browser registry entries as directed, activated ' Troubleshooting / Safe Mode' contingency and STILL can't download anything (additionally, tried to do so with and without limited-time Malwarebytes web protections).....want to CONTINUE using Version 95 because by ALL indications and from what I'm seeing in Comments, my instincts about newer ones - were sound, WELL-informed.....please advise ASAP? Thanks!

Hi there,

I have a brand new Win 10 MS Surface 4 Laptop, and have tried downloading and installing various versions of Firefox:

From the the Windows Store Direct downloads (via MS Edge): Mozilla FF Win 64 Mozilla FF Win 64 MSI Mozilla FF Win 32

I have completely uninstalled and attempted to re-install each in turn. Attempts to open FF through desktop shortcut, Start Menu and Win-R FF.exe all seem to start but only ever get the briefest flash of a blue line along the Taskbar then nothing. Same happens starting Shift-Shortcut.

Nothing shows in Task Manager either after any start method. I'm pretty sure I'm not in 'S Mode' as I've been able to download, install and run WhatsApp Web, but I'm not wholly convinced I've cleared that up fully.

Thanks! E

Hello,

I have been trying to use Firefox and it won't load, the page just doesn't load to firefox. I have Mac OS Monterey 12.0.1. I have deleted the app and reinstalled it but nothing works. Someone, please help!! The browser doesn't work it won't open.

Windows 10 - Lenovo Thinkpad X1 Carbon This fall after an update attempt, Firefox started trying to update every time it was started. Deleted Update files in Program Data. FF would restart normally one time. Update data files were always replaced and the update on every startup continued - over and over and over. Tried refreshing FF- same thing. Uninstalled FF this AM and tried to reinstall when I get the following error:

XULRunner Error: Platform version "94.0.2" is not compatible with minVersion >= 94.0.1 maxVersion <= 94.0.1

No FF - HELP!

All of a sudden Firefox has ceased to react when I'm trying to download a file/save a page. When I click Cmd+S or File → Save page as…, nothing happens. When I try to open an upload dialogue, a solid gray window appears, and that's it. Uploading files through drag&drop interface works fine.

The problem seemingly appeared after migrating from a Mac Mini to a Macbook Air (both M1). I've already tried to restart the laptop and refresh Firefox — to no avail.

Is there anything else I could try to do?

I work on computers without admin rights, and i can't install add-ons,

how to make a true portable Firefox without using registry at all

I really don't understand that a free software allows such a blocking, even if chrome doesn't pose any problem with add-ons.

is there a way to lanuch firefox with a option to not use registry or to redirect registry in file or in a not locked custom registry like

hkey_local_machine/software/policies/Mozilla_portable/Firefox

or something like that ?

I HAVE COMPLAINED BEFORE ABOUT THIS- \bing-ebay-google-wikipedia-amazon - CONSTANTLY -- DOWNLOADING ONTO MY FIREFOX - AND I DID REMOVE ANY THING CLOSE TO bing-ebay-google-wikipedia-amazon- I NOTICE SEVERAL PEOPLE ARE COMPLAINING ABOUT THIS PROBLEM- SO REMOVE THAT CRAP ADS OR I'LL FILE A FORMAL COMPLAINT- I WILL MAKE SURE THAT PEOPLE SEARCH THEIR FIRE FOX. THANK GOD FOE UNINSTALL TOOLS THAT CAN TRACK AND FIND YOUR SECRET AD ONS- NO ONE SHOULD HAVE TO SEARCH OR WORRY ABOUT FIREFOX PUTTING JUNK ON THEIR BROWSER- YOUR STATEMENT OF TRUST STATES THAT FIREFOX WILL NOT AD JUNK OR UNWANTED ADS.

I am testing FF91esr for deployment later this year. Having a lot of grief with it.

For context; On most of our PCs the profile folder is NOT in the %APPDATA% folder. It lives on a different drive, typically drive F:\

This allows us a lot of freedom to restore a users C:\ drive without messing up the Firefox profile, or losing recent information, for example. We do the same for Thunderbird and several other applications.

The profile.ini file does live in its default location and points to the relavant folder path=F:\Users\<username>\profiles\<profilename> IsRelative=0

We backup a users PC with a comprehensive script which copies the profile.ini and Profiles folder. The group policy is also backed up, and in that policy we have set to use legacy profiles.

When we build a new PC for a user we restore those backups in the hope that the user will take up where they left off. For example, their browser history will be at the point is was when they left the PC.

The whole process is pretty automated. However, with FF91esr I cannot get it to use the folder we backed up. It ignores what's in the profiles.ini file and creates a new profile in the default location, set's it as default and of course sets IsRelative=1.

I tried several combinations of things to try to stop this, but in the end the ONLY way I could get it to use the restored profile was to go to about:profiles, create a new profile, point it to the folder where the restored profile is located, restart using the new browser, then via about:profiles, delete the bogus profile (of course having set the restored profile as default).

I'm not going to sit at 250 PCs doing that. It's crazy.

How can I get FF to use the restored profile folder and stop it endlessly creating new profile folders?

So far I've only tested with clean installs of FF91esr, so this is not an issue with different versions of profiles. But I am concerned over what's going to happen when I update Firefox on a PC...

I just recently updated my Macbook Air to Big Sur and downloaded Firefox to use as my default browser. Installation went smoothly and I am able to use the program as intended. When I click on an external link, an window pops up and tells I do not have permission to open the app and to contact my computer or network administrator for support.

I am not computer savvy when it comes to programming and would love any help anyone has to offer.

Most appreciative.

Hi there, I'm having trouble opening firefox that suddenly didn't open after I've used it as usual. When I've closed it, I've put the macbook on sleep mode and then reopen it after 10 minutes and tried to open firefox as always. It didn't. I'm trying to figure it out and I've followed all the possible paths on Mozzilla's support and others blogs, but none of them worked out. I've tried also to uninstall and re install firefox from scratch, but nothing happens: I still get the message. At this point I don't care if I need a fresh start, I have a bookmark's backups so, how can I really uninstall Firefox and install it from the beginning? Is there a hidden folder I'm missing? Thank you in advance

I was switching my browser from Brave, a chrome based browser, back to Firefox because Brave doesn't can't run some of the stuff my uni learning management system (LMS). I tried importing my browser bookmarks and passwords to Firefox but the importing feature on Firefox doesn't show Brave as one of the browsers it can take the data from. I want to know if there's anyway I can fix this or if there's no hope for importing data from chromium browsers to Firefox.
