Firefox Support Forum

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Later version refuses to connect to my modem, and goes into security web mode. This modem uses HTTP/HTTPS for access, i.e., connects directly it's IP address, then the user enters a username and password. At that point, the the modem switches to HTTPS for control.

With this recent update, there is NO WAY to access the modem for any work, or upgrade the HTTPS certificate on the modem. This is a BUG.

What should happen is that if the web site will accept a HTTP connection, Firefox should NOT refuse connection or test for security issues UNTIL the user or the device switches to HTTPS.

As an aside, I've used Firefox on this Zywall modem for years until recently.

Videos can't be played at higher playback speed Bug

On firefox, I cant play videos at higher playback speed or it'll only play audio or video will endlessly buffer. Using user-agent spoofer and changing to chrome makes it a little less worse but still the problem sustains. On Brave, the video doesnt have any effect of higher playback speed rather it'll make the video buffer and have very strong red contrast.

I want to use the search field for search and the adressbar to enter adresses. Unfortunately it doesn't let me enter adresses, they all get routed to a search provide (google) and I can't acees my router

How can I dsable the search in the adressbar?

Setting browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar (are you kidding me?) to flase does not help

I often drag elements on trello.com. Whenever I drag an element, that element seems to double in size, making it hard to see what is underneath. Attached is an example.

I believe this is related to the fact that I am running Linux/X11 and my DPR is 2. From about:support:

• Window Device Pixel Ratios 2,2,2,2
• Window Protocol x11
• OS Linux 6.1.0-13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.55-1 (2023-09-29)

Is there an about:config setting or anything that will prevent scaling dragged elements?

The Firefox "New tab" page shows quick-navigation buttons. At the top right of each button, the 3-dot menu has an Edit option. On the edit dialog is a link "Use a custom image", which then prompts you for a image URL.

I've tried pointing this to images in my Google Photos (a 1024x1024 .JPG), using an open-shareable link, but it doesn't work.

a) What format does the icon image have to be in? b) Are there any limitations on the URL? c) Is there a way to use a locally stored icon image?

Any guidance would be most welcome! Thanks :)

Hi, I am using Firefox vsn 120 for Linux Mint. I believe that I have the privacy and security set with the default settings.

However, Firefox seems to forget the information stored by websites, so that can't simply login.

Each. And. Every. Time. I have to go through the process of re-introducing myself to the security of the website provider who insists on sending me emails, SMS messages, etc. with codes to confirm who I am.

This applies, every time I use a site that requires a login (bank, BBC, Fidelity, eBay, Facebook....).

Once I have been approved on a site, then my login seems to work for a few days, up to a week and then off we go again with a new set of security codes. My settings do not delete cookies, and firefox is never closed, except if the PC needs a reboot, which is rare.

I would appreciate any help in settings that would allow me to use Firefox normally without having to enter security codes. Cheers, Mark

So to cut it short, i have an issue with not just firefox but almost all other browsers too. I have tried Firefox, Chrome, Opera and Edge. Both Firefox and Chrome will instantly close when i open them. As in, the window will open and immediately close after barely half a second. This has happened with Chrome and Firefox, yet Opera and Edge dont seem to have this issue. I am a Firefox user normally so this does make it a little annoying. Any ideas on why that is?

I can't download anything anymore. I get the "failed" message. I see in support questons that this has been going on for a long time even though there have been repeated "fixes" reported. I've used Firefox for a long time and really prefer it, but I'm having to change to Chrome to be able to complete my work.

Running Firefox 120.0.1 on Windows 10. I also run Vivaldi and test with Chrome. I installed Google Analytics Opt-Out add-ons on FF, Vivaldi, and Chrome. When I go to any site with links to X (Twitter), and click on the link, instead of that link appearing the last X link I went to appears. If I click again I get to the correct link.

When I disable the Google Analytics Opt-Out add-on all works fine. This doesn't happen with either of the Chromium browsers, so I'm thinking there's something happening in Firefox by avoiding Google analytics that isn't in the Chromium browsers. In addition, this behavior began within the past couple of weeks of recent FF updates.

I installed several different Google Analytics add-ons and the same thing happened in FF, but not in the Chromium browsers.

Any ideas? I know I can disable the analytics crushers but I really don't want Google hijacking my browsing.

Stop tabs from automatically refreshing to top of page. Many people have this problem and I don't find a fix. One article states to go to Options and "Warn me when websites try to redirect or reload the page," but I can't find options.

I am using Firefox version 119.0.1 (64-bit) on Ubuntu 22.04. Using this version of Firefox, as well as previous versions for the last few months, I am having a persistent error when using Google Advanced Search. I enter search criteria into the field “Find pages with … all these words” and successfully progress through a chain of web pages. Previously I was able to backtrack to the previously mentioned field and find my search criteria, then edit the text, and carry out a modified search. For many months this field has been blank when returning to it. So it is now necessary to re-enter all text for a new search. This is very frustrating. I have experienced this problem on the three computers that I regularly use.

I have found that when I use the Google Chrome browser the problem goes away and searches progress normally. I would much prefer to use Firefox as my browser as I find its bookmark system superior. The truth is that if this problem with Firefox can’t be fixed soon I will be forced to migrate to Chrome. Can you please help me resolve this Firefox problem?

I just updated my Firefox browser. Now it doesn't work: "tab is crashed" - an endless chain, always again this.

You should try harder to release bugfree software ...

What about short-time help?

Since the latest Firefox update a few days ago, I am not able to log into my Outlook/Webmail account; nothing happens.

I can access it on google chrome but not on Firefox.

I use a MacBook Pro. I recently created a new profile for Firefox (for work purposes) and set it as the default profile, because I'm trying to get off Chrome entirely. The preexisting no-longer-default profile contained all my "personal" data - bookmarks, extensions, etc. Continued using both profiles for about a week with no issues. Last night my MacBook updated and when I reopened Firefox, the new default profile was fine, but when I went into about:profiles and launched the secondary profile in a new browser, it was completely empty - no history, no bookmarks, no extensions, nothing. That's at least a year's worth of data completely gone. I've looked through support articles and past folks' questions and am just completely lost as to how to restore it or what went wrong. If it's not possible to restore that data, how can I at least prevent this from happening again? I've very much lost trust in Firefox profiles because of this. Help please?
