Firefox 技術支援討論區

Since few days I experienced a strange beaviour on my firefox:

if I press and keep pressed a key, say backspace or left arrow or just a letter key, then usually I see repetitions, e.g. fast erasing back, fast moving back and forward or just typing something like:

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

In my gmail composer this does not happens anymore, and if I need to erase a word I need to repetitely press and relase backspace key.

I erased firefox and make a fresh install, via snap, with completely new profile, but the problem remains. It does not seem to appear on other places, for instance when typing this question everything is fine. If I use gmail with other browser (same pc) then all is fine.

I have ubuntu with all updates regurarly installed, uname -a give me Linux mypc 5.15.0-101-generic #111-Ubuntu SMP Tue Mar 5 20:16:58 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

How can I fix this? Where I have to look?

Firefox doesn't close correctly. PC on Windows 10 freezes up. When I go to Task Manger, I see Firefox has replicated sometimes as many as 5-10 times or more at same time. I close down the FF tabs, try again to open FF, freezes again, re-open Task Manager, and it has replicated again. Can't seem to find cause or solution. Any suggestions? I have tried uninstalling FF then re-installing, but that doesn't work. BTW, same exact thing happens with Chrome, Duckduck, or Edge (which I despise), which tell me it's an issue with my Windows 10 computer, not with FF. TIA.

Automatic redirecting Firefox redirects to "https://www.google.com/?gws_rd=ssl" every time I am trying to open any page on a website. The page disappears after a second or two. I can open it with old version of Google Chrome or new Opera but not in Firefox. I have been visiting this website for years and now I can't. It happens in any version of Firefox I have installed.

Advise how to get rid of the display streaks Regardless of page, angular streaks will obscure parts of the display (doesn't happen with other browsers, restarted my machine, cleared my cache, not sure how to correct it? Thanks

Firefox keeps crashing whenever i open a file (i.e. Cpanel) etc. I can open web links etc fine.

Crash Reason EXCEPTION_ACCESS_VIOLATION_READ Crash Address 0x0000000000000000

Not having this problem in either Edge or Chrome.

Was working fine for months until today.

Have tried new profile and refreshing windows / rebooting etc - no joy.

Any ideas?

Cheers, Dean.

As described in the title Firefox instantly closes after opening it. I can see the window opening for half a second but then it closes again. Same with Troubleshoot mode. New installation of Windows 11, new installation of Firefox, only the standard antivirus from Windows. I don't know what could pose an issue except maybe some corrupt data that was downloaded from Onedrive although I already deleted the profiles in the AppData folder.

Hello.

Can someone please help me to fix Firefox. It's terribly slow and sometimes gets stuck. I've opened the task manager and see multiple processes that don't look right - please see the attached screenshot. How can I fix this? I'm using version 124.0.1 on Windows 10.

Thank you. Johan.

Firefox runs fine most of the time. If I right-click to download an image, or click a link to download a PDF or other file, or Save HTML, I see the "Save file" dialog, click Save and then Firefox freezes up for a while, maybe a minute or two. Pages won't scroll. I can't switch tabs. I can bring up a different firefox window and it redraws its contents, but I can't scroll or do anything else.

This didn't happen a month ago, then one day after a system upgrade, it happens every time. I'm using FF 123.0.1 on Arch Linux. 64GB RAM, so it's not a memory shortage. I have upgraded one or two times more since the upgrade when this appeared. Chromium is not affected, Thunderbird is fine, and all other software continues to be fine as before, including when saving files. Only FF has this problem.

What is the problem and solution? Are there ways to gather more info to diagnose the problem, if needed?

the Icons code on github in this file are not correct rendered in Firefox. If I use these icons in my terminal they will get rendered in the terminal.

• fonts-font-awesome is installed
• Allow pages to use their own fonts is enabled
• all addons are disabled
• security.sandbox.content.level 1
• gfx.downloadable_fonts.enabled true
• use hardware acceleration available enable/disable makes no difference

• Ubuntu 23.10
• 6.5.0-26-generic
• Mozilla Firefox 124.0.1

Every time I try to use Google Docs, Gmail, or use ShelterLuv (I work at a shelter), either the tab crashes or the whole browser does. I try to upload images onto ShelterLuv, but once I click "Browse" to view my pictures, the whole browser crashes. It is making it hard to do my job.

Crash report (most recent): bp-2ae75fbf-b2c6-4419-93fb-9ee600240401 That one is from me trying to upload an image onto ShelterLuv.

Thanks in advance.

Hello,

Firefox YouTube HDR mode works in Full Screen Mode (FSM), Picture in Picture (PiP), but not in normal Windowed mode (WiM). This bug appeared in around Q3-Q4 2023, before that the YouTube HDR mode was available in FSM, PiP and WiM mode.

In Safari the YouTube HDR content works in FSM, PiP and WiM mode.

Firefox keep crashing when I use certain websites (realtor.com is one that comes to mind). I use a Macbook pro. I've updated my operating system, updated Firefox, and tried to use Firefox in troubleshooting mode. Everything is up to date, and the crashes still happen in troubleshooting mode. Here's the crash code: bp-80317ed2-74bc-4df1-a867-a6a130240322. Any ideas how to fix this? Thanks a lot.

since my last upgrade 124, I cannot open most of the shortcuts on my desktop What can I do to stop this I get the NON COMPATIBLE ERROR msg If I go to OPEN WITH... and use another browser, it opens. Do I need to delete firefox and go to another browser??

Windows Updates (KB5035845) and 10.0.19041.4163

After these latest updates, EVERY, Firefox browser (derivatives included, i.e. LibreWolf, etc...) are opening VERY slowly. Its almost like the browser is freezing while opening for around 10 - 20 sec, then opening. It used to open within a second or two. If I uninstall the updates the problem goes away, BUT, windows re-installs them automatically. After it is up and running its ok. The problem seems to be on startup only.
