Firefox Support Forum

Typing the problem in the quote marks in the search box yields over 400 identical questions. So obviously this is a known problem with FF, and hopefully with Mozilla.

With me it happens on Facebook. Clicking "wait" basically does nothing, clicking "stop it" it basically stops the page from loading, so you can't post a message or have any interaction with the site whatsoever.

All along I'm watching the CPU at a constant 50%-60%, and memory for one tab of FB going up steadily from 400 MB to 1.2 GB (almost like a memory leak).

Now, my laptop has really limited specs, 3 GB RAM, Win 7, 10 years old. So I thought the laptop is probably to blame. Till I did the following experiment: Let's try Edge, with the exact same tabs, exact same sites.

So, one tab of the same FB page + one tab of Yahoo Mail -> FF: 60% of CPU, 1.5 GB of memory (and counting). Edge: 10%-15% of CPU, 500-600 MB of memory, and FB smooth as silk.

Any suggestions/solutions are welcome.

Hi, Using the updated Firefox on Windows. The Delta home page works but when I do a search, the results don't load. "We're sorry there was a problem processing this request. Please try again" This has been going on for about a week. I set cookies to be allowed from Delta and there is no difference. Please let me know your suggestions. Thanks, Michelle R

Here's how I discovered this issue.

PayPal has a page on which the user selects a method for having money withdrawn from one's PayPal account to one's bank. I've found that this page's "Next" button works correctly (that is, it loads the page on which the user would then indicate the amount to be transferred) on Firefox 40.0.2, but it works incorrectly (that is, it only underlines the word "Next" and does not load a new page) on Firefox 52.9.0 and Firefox 87.0.2. (My internet access in each case is dialup.)

After pursuing various leads on the possible cause, it occurred to me to inspect the page source for the "withdraw" page for each of those versions of Firefox. And I discovered that the page source displayed by Firefox 40.0.2 contained content that was absent from the page source displayed by either of the other two Firefox versions. Some of this content appeared to define a function that returns content to the server when "Next" was clicked. If true, this could certainly account for why clicking the button didn't do what it should.

I noticed that the page source uses as many as 12 nested levels of <div>-</div> elements, which seems counter to the advice I read at an HTML standards page (at whatwg.org). But I don't know whether this could be a factor in the behavior I described.

I've copied the page source for each Firefox version and pasted them into text files, but I wasn't sure it would be appropriate to post them publicly. I would be glad to provide them offline.

Thanks for any help or suggestions.

I have Pinned several websites that I visit often to the TOP SItes on my FF Home Page. They randomly disappear or shift from where I place them. Why are they not staying in place when they are "Pinned"? Annoying that I have to continuously do this. I am using FF Version 87.0

DDG search term entered is, as an example, "asus strix gtx 750ti 4g kaufen" (problem happens with any search term). Paging down in the list of results, I get many hits that a seemingly "routed" over a misused URL (which as the search term addended to it). Selecting such a result always brings up the same "strange" page with "pointers" to amazon. Leaving the page puts me automatically on the unwanted amazon page.

It is very annoying. Happens with more or less all search terms.

No virus, at least BitDefender full scan says so. I'm using private mode, HTTPS on and Ublock origin. Haven't changed my method of searching - this problem exist since a few weeks (MZ since v.86). Chrome and Opera work fine - they say either "503 error" or "page not found" ...

How can I fix this - maybe the uploaded image can help diagnose the problem?

After installed some expired certs on a server in house, I try and bring up a management page that worked fine prior. The error is: The server presented a certificate that contains an invalid encoding of an integer. Common causes include negative serial numbers, negative RSA moduli, and encodings that are longer than necessary.

Error code: MOZILLA_PKIX_ERROR_INVALID_INTEGER_ENCODING

How can this be worked around, a setting of some sort maybe?

Thanks for any input

Just added New Tab Version 1 to Firefox version 72.0.2 with DuckDuckGo as Search Engine and default page.

When I call for a new tab I get the message - "Access to the File Was Denied" and "The file at moz-extension://7b4a03b3-0438-454e-bf65-9629bce7ae58/newtab.html is not readable."

However, if I then click on the Firefox Home Page Icon (little house icon) I get straight to the Home Page with the search function available.

Anyone know why I get this interim error message, or why I don't get transferred straight to the Home Page?

My Navy Federal Credit Union did a major update to their system today 04/07/2021. After the update I was no longer prevented from logging on w/FF87.0 private window. Saw others having many problems similar to mine & you might mention to them that FF87.0 may now be more advanced than the various systems that they are not able to login to after the FF87.0 update. I was using MSEdge to access my blocked sites & almost went back to FF86.0.1.

Problems with Youtube full screen not working persist. Could be a spyware tool embedded by Google that is broken now. Not a big enough problem to force me to roll back version of FF. Saw many others were having online video problems since update. I don't have an answer for them.

Guessing as privacy protection increases our access problems will also increase as hacks, spies & adware try to battle back. Me? I like my privacy & thank Mozilla folks for their great work. God bless one & all. Stay safe.

Hello, I use Windows 7 with a Gateway computer. On the "new tab" page I pin sites,but, they are removed sooner or later for new sites. When I pin a site , I expect it to remain . So, even if I do not visit a site for a long time, is there a way to keep my pinned sites from being displaced ? Also, instructions say, "to show more or fewer top sites" to hover until the edit link appears. I try hovering all over but can not get the edit link to appear. Any help will be much appreciated. Thank you
