Firefox Support Forum

Hi,

I have a policies.json file that acts as a white list for me (black listed all urls and then white listed needed urls). I was wondering is it possible to create a second .json file that will act as a black list. I want to give access to a partial admin. user to the policy.json file to be able to edit the file and add websites if needed but I want a another black list running as well to block out specific websites (this one the partial admin. will not have access to).

So to start off the first question would be is firefox only limited to one .json file for policies or can you have multiple .json files (I want to call the second file blacklist.json)? Btw I use Debian and Firefox-esr.

Thanks.

In a simple HTML file containing an Arabic / Urdu / Persian phrase: "با نشئہ درویشی در ساز و دمادم زن", Firefox in Linux (Ubuntu, to be more precise) uses the default font (DejaVu Sans) for the whole phrase except for one character (UNICODE: 6C1). Font used for this character is Noto Sans Arabic UI. So the text looks broken due to different fonts.

Please have a look at the attached screenshots for better understanding.

I've tried to search but could not find how exactly Firefox resolves preferences in Font Settings and CSS "font-family" preference to local fonts in Linux. Does this have to do something with "fontconfig"?

How can I make Firefox use only the default font for the whole phrase?

Hi,

Firefox reports an incorrect timezone (UTC), despite `privacy.resistFingerprinting` being false. (None of the settings underneath `privacy` have been changed.

The clearest example is here: https://browserspy.dk/date.php (screenshot attached). Another browser (epiphany) reports the correct timezone on that page.

I have tested the following versions: - Mozilla Firefox 102.11.0esr - Mozilla Firefox 113.0 - Mozilla Firefox 113.0b9

It persists under `--safe-mode`, in Private Browsing mode and despite being signed into a firefox account or not.

uname -a: Linux s 6.3.4 #1-NixOS SMP PREEMPT_DYNAMIC Wed May 24 16:30:25 UTC 2023 x86_64 GNU/Linux

timedatectl, displays correct timezone

I'm at a loss at how to proceed and debug this, every search leads back to privacy.resistFingerprinting, but as mentioned this isn't the case here.

The Samsung page with the products registration: https://www.samsung.com/us/support/account/products/

does not display any products on Firefox and keeps refreshing itself about every 10 seconds or so.

It works perfectly in Chrome on the same computer and then displays the individual Samsung products I've purchased and registered with Samsung.

I am building a website on my hard drive just using files. EX: file:///home/username/notes/main.html <a href="/home/username/folder/file.txt"></a>

I put an anchor link in the html source , and when I click on it I want it to open file.txt with gedit. I can get c files to do it , but .txt files open in Firefox.

Summary: Firefox fails to load many sites, and some will kill the entire browser.

I recently updated from Ubuntu 22.10 to 23.04, which included an upgrade to Firefox. I originally had trouble with tab/window dragging operations causing the entire desktop to crash.

Removing the snap and installing from the Firefox maintained PPA fixed this issue, but a number of others remain. (Detail on this part over here on the ubuntu forums if interested)

Now many google sites simply show the loading error for ever and never recover. Some URLS can kill the browser completely. For example, this one from the Mozilla website: https://support.mozilla.org/en-US/kb/websites-show-spinning-wheel-never-finish-load The error message is attached.

I am happy to perform more tests and provide more diagnostic if it will help. That same URL works fine from the chromium browser on the same desktop systems,as does every other site I've had issues with.

I am working on a new computer with Kubuntu and have FF installed via .deb.

On my previous computer, I could drag files from the downloads dropdown (eg download a file and then drag it into gmail as an attachment).

Now this is not possible. Instead, I need to go to the downloads folder in order to drag and drop a file. An extra step and rather annoying.

The problem is persists in Safe Mode.

Is there any way to get the old functionality back?

I use Firefox on Ubuntu 22.04, and my system has 16GB RAM. I have been facing this problem of frequent crashes for the past few months. By crash, I mean not Firefox alone, but the entire system. I use several apps and run several processes that require great compute resources, often simultaneously. I have narrowed the cause of frequent system crashes to Firefox alone; the system rarely crashes when I use other resource-heavy apps. Due to this, I have to restart my system several times a day.

Before this problem arose, I would use multiple tabs (including YouTube, often 10+, close to 20) and multiple windows (2+). Such usage very rarely caused crashes, which is why it is surprising that Firefox now causes the entire system to simply hang sometimes with as low as 3-4 tabs.

I have disabled Hardware Acceleration, refreshed Firefox, even tried disabling WebGL. I also tested it after removing all add-ons, but it still didn't help (I use only 2 add-ons: a simple wide-spectrum ad-blocker and an EPUB reader). Even in troubleshoot mode, Firefox will cause my system to heat up, although it takes some more effort to crash in this case. I use one of the standard themes, so it could not have been the problem.

Many people report Firefox crashes, but in my case, Firefox causes my entire system to crash. How do I fix this issue? Thank you in advance.

When I print to a PDF file, Firefox changes internal links (#go-there) to full external links (either https://the.website.tld/paper.html#go-there or file://home/me/paper.html#go-there).

This is obviously wrong, since the links are internal to the document.

How to I change this behavior?

Thanks.
