My installation of 32-bit Firefox 102 had been repeatedly crashing, sometimes for no apparent reason. I decided to download the 64-bit version of Firefox 102, uninstalled the 32-bit version, carried out a standard installed and all this appeared successful. I noticed that I was getting a lot of advertisements and remembered that I had had Ghostery installed as an extension in my 32-bit Firefox. I went to the extensions page, selected Ghostery and asked for it to be added. Shortly after that, I got a message that the installation had been aborted because the extension might be corrupt. I tried again and got the same message. I tried another ad blocker, and got the same message with that one; and tried a third with the same result. What is going on? I haven't changed any settings in Firefox since the standard installation, and the extensions were from the Firefox source, so how can the extensions be corrupt? If it isn't corrupt, why isn't Firefox installing it?

I am getting an error that Firefox is not supported on some websites. Is there an add-on or extension that can make the site think I am using internet explorer or edge?

Hi, I use Verizon Fios and a Windows 10 PC. Firefox is my default browser. I don't experience any of the problems described below when using Chrome, which I only do now that Firefox is not working optimally.

In many, many years I've never had trouble with Firefox until about a month ago. When I opened the browser, I received messages -- about five times -- that it had crashed. After that, many websites now load very slowly, or not at all. And now, I'm unable to see product images on Amazon.

Would you please help me? I'm 84 and not all that computer savvy and I don't want to delete my browsing history, etc. Many thanks, Valerie

Hi all, I'm having a lot of problems with Firefox crashing pretty often. Sometimes once or twice a day.

I most often see crashes in the middle of a Webex video conference for work. But Firefox sometimes goes down in other situations that I see no pattern in.

This is Ubuntu 20.04, Firefox 102.0. Unfortunately, it's a complex environment to debug.

First, when firefox goes down, it rarely leaves a crash report behind. So I'm not getting any direct evidence as to what is happening. Second, I run with uBlock active and it is very difficult to function in the browser without long enough for the crash to happen. Third, I typically have several hundred tabs open. I have a lot of memory (64G) in my machine, and the machine doesn't act like it's swapping, so I don't think I'm running out of memory.

Any help getting to the bottom of what's going on is welcome.

Specifically within the Firefox browser, I cannot access Reddit.com or other affiliate links. I am just getting a completely white screen, doesn't even say "Blocked". However I can visit Reddit in other browsers, with or without a VPN, while a VPN doesn't even change the outcome within the Firefox browser.

Any help would be much appreciated, thank you.

I recently started having this problem. I open a couple of web pages and then can't open more without restarting and logging in again. I have cleared caches (no help) and reset (ditto). I have used Firefox for a long time and never had any problem.

Whenever I try to open a pdf file (automatically opened in Acrobat), Firefox hangs a long time, before eventually opening it in Acrobat.

When I open the download dialog, it always shows the file is almost downloaded, but the progress bar always hangs near the end. When I go to the download folder, I always see the pdf I'm trying to open with a filesize of 0kb. This behaviour is the same for large and small files. Eventually (after several minutes), it just opens as it should.

I already tried reinstalling Acrobat.

The behaviour is the same in regular Firefox (102.0 64-bit win7) and Firefox developer (103.0b4 64-bit win7).

It is specifically with pdf files. Other downloaded documents seem to open as it should.

Can someone help me to trace and solve the cause of this issue?

Hi,

When I connect to my desktop via RDP, Firefox is crashing on my desktop. It has began after updating to last versions. Current versions are Firefox 102.0, Windows 10.

Thanks.

Recently got a new computer with Windows 11, and now whenever I try to play a Youtube video or videos on other sites, Firefox as a whole slows down. There is a delay when starting the video, and at times Firefox stops responding if I try to switch to another tab when this is happening. (Not always, but sometimes).

The delay can be anywhere from 5 to 45 seconds or so, and repeats whenever I pause and unpause a video, or even rewind slightly. This doesn't seem to be buffering, and videos seem to work just fine on Edge. Any idea what could be causing this issue?

Cannot open PDF from MS365/Sharepoint site. Error message: "ERROR: URL provided is expired or invalid. Please reinitiate the workflow..." Checked:

1. 1 Other file types open/download correctly.
2. 2 Other browsers open PDFs correctly.

The issue seems restricted to Firefox and PDFs.

Screen 1 message: firefox.exe Entry point not found. Files(x86)Mozilla.firefox\xul.dll. Screen 2 message: couldn't load XPCOM. After repeated tries to get to firefox I deleted the icon and re-installeed a new copy of firefox.

As my computer skills are not great my question is can any of the old data/bookmarks be retrieved? And if so

how in very simple terms/pictures.

after updating 102, I noticed that when I wanna download file from websites, after I click Save or Cancel in the dialog, my Firefox will get no response for 1-2 seconds, I have tried troubleshoot mode, cleaning cache, but both not working.

Thx.

Hi, this is a minor problem and more a quality-of-life thing, as there is no hard crash or bug per se. Context: I need to print a LOT of things every month for the job, so I download a LOT of PDFs.

Problem: When downloading a PDF, if I open it via the dropdown menu in the menubar, it opens, but immediately unfocuses Firefox. That's it. Why the unfocusing? Lol.

Limits: If I mark PDFs to open automatically (in the options) instead of downloading, then it opens fine and no loss of focus. Same thing if I open from a folder, it's set to open in Firefox and it does so, with no loss of focus. As far as I can tell, the issue appears only when opening from the download button/icon/dropdown menu from the menubar.

Suggestion 1) Adding a "Download AND Open in Firefox" option in the settings would be my ultimate greatest option but.... maybe not the best for cluttering millions of people's browser options. It's just what "I" want to do ;)

Suggestion 2) Trace where it loses focus and re-focus / prevent loss of focus when opening from the menu.

I have found that my Fiefox cannot handle live news streaming and video playback and the picture freezes but the sound continues. This has been going on for years but I do not have a problem with any other browser.

Firefox was working fine yesterday. But all of a sudden while playing a youtube video it started being choppy. It drops frames, scrolling and video playback are choppy and laggy, there is lag on button inputs, the system is choppy and laggy too while firefox is open, especially when video is playing. I checked the CPU and GPU usage and I can't see any spikes. I have tried refreshing firefox but that did not fix the problem.

OS is manjaro linux (gnome version) latest. Firefox is also at the latest version.

Hello, I have a problem with firefox and it's recently unable to open Google and Youtube due to HTTP Strict Transport Security (HSTS) with an error Code : SEC_ERROR_UNKNOWN_ISSUER

I have done the steps in here : https://support.mozilla.org/en-US/kb/error-codes-secure-websites I don't have any third-party Antivirus

I have also do about:config security.enterprise_roots.enabled by changing to true. It works but unfortunately youtube is broken when i set it to true.

I can't also accept the risk and continue since there's no button that says it.

Thank you

Immediately following a Firefox update I began having scrolling problems on my Facebook page. I am able to scroll down normally to a point, and then, all of a sudden, the scroll bar will go up and immediately go back down without me touching the mouse. It will continue doing the up and down scrolling indefinitely and at a high rate of speed. I have tried turning off auto scroll and smooth scrolling at the browser, but no luck. I have Windows 8.1. I have never heard of anyone else having this problem so this seemed like my only option.
