Issue description: Similar as https://support.mozilla.org/en-US/questions/1294366 But I'm not using USB wireless receiver, I'm using wired network adapter for connection

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.

I saw through several threads on how to try and fix this issue but none seem to work for me, when im trying to watch a video on regular firefox it doesnt work but on safe/troubleshooting mode. and it works when i put the video in a new tab but not on the main site. and while looking in the console i get this "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://static1.e621.net/data/ab/71/ab71a84c62b9d77fa0eb68c5e64dc165.webm. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 206. any help will definitely be nice

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

I've got an M2 MacAir running the latest version of Sonoma. Within the last week, the battery power has fallen off a cliff. It barely runs for a couple of hours and recharging takes nearly half a day. I'm not running anything unusual just social media & YT videos. This seems to have coincided with the latest Firefox update. I was wondering if this might be contributing to it or if this is a common problem since Sonoma & FF updates?

Anyone any ideas?

I have at least some computer knowledge but not enough to understand the link on the crash report that says what this report means. Is there a cliff notes version of why my firefox keeps crashing. I have link to the page so I am not sure what info is needed to help me. I can give screenshots or link info. I'm not sure if it's safe to post everything on report or what is necessary.

it keeps popping this message up "firefox is installing components needed to play audio or video on this page, please try again later" its been saying this since the new update and keeps telling me failed to check for update.

I keep getting this message every time I try to access a website I haven't accessed for a while : see attached graphic.

How can I get this to stop ?

I can't open firefox. message says "firefox quit unexpectedly" and it won't reload. I tried Force Quit. I tried restarting my computer. I tried completely shutting computer down and restarting. It happened very suddenly yesterday.

I recently purchased a new Mac Book Pro. After migrating my data from my old one I noticed that when using Firefox my Facebook account was not working properly. I no longer could access my own page or the pages of friends. However, I could access some group accounts I'm associated with. On Safari, everything works fine. I suspect something must have been compromised during the data migration.

I deleted the Firefox app from my new computer and then reinstalled it but to no avail. When I'm in Facebook and try to access my page I get an error message. My OS system to up to date and apparently my Firefox is up to date as well. Any suggestions? Thanks!

I am receiving this error message when I try to log into my router. My router has a certificate from Let's Encrypt.

What settings do I have wrong?

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

I saw a message that my Add-ons were disabled, and when I checked the Add-ons Manager , each of my many Add-ons had a message similar to: "1Password – Password Manager could not be verified for use in Firefox and has been disabled. "

Some searches in the forums suggest that that this can be caused my a certificate at Mozilla expiring, I seem to be the only one with this issue at the moment. All of my Add-ons came through the Mozilla store .

I am using version 123.0.1 (64-bit) on OpenSUSE Leap 15.5, and as far as I can see all of my updates are current (and from the official sources.)

What should I do next? I expect I need to wait for a certificate update or something at Mozilla, but if/when that happens how do I verify it did and re-enable my add-ons?

I run the latest Firefox (v122.0.1) on Windows 11.

Since last week, FF takes 14 minutes to start the first time after a boot. :-( Usually FF starts in ~3 seconds.

I reboot the laptop. I wait a minute. I start FF. Nothing happens for 14 minutes. Finally the browser window suddenly appear and everything is working normally. I exit FF (no remaining firefox.exe processes are running). I start FF again. Now it starts immediately as usual. :-) But: I reboot and start FF. Again, it takes 14 minutes to start. This is reproduceable every time.

I haven't tried to *solve* this by refreshing FF or simillar. Right now I'm more interested in debugging this and finding out what is wrong.

I found https://profiler.firefox.com/docs/#/./guide-startup-shutdown which states how to automatically start the profiler at startup.

12:40 I boot the computer, login and wait a minute. 12:43 I start CMD.EXE and run:

 cd c:\Program Files\Mozilla Firefox
 set MOZ_PROFILER_STARTUP=1
 set MOZ_PROFILER_STARTUP_ENTRIES=20000000
 set MOZ_PROFILER_STARTUP_INTERVAL=100

12:44 I run:

 firefox.exe

No GUI appear. (it won't appear until 14 minutes later) I open the Task Manager and see one (1) firefox.exe process, taking 0% cpu. (pid 17668) 12:48 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:50 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:52 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:54 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:56 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:58 The browser GUI finally appear. Everything is now normal. It is showing one (1) tab with my start-page (google) just as it should. (my Task Manager now show 12 FF processes running, with various options) 12:59 I click the icon to stop the profiling.

I open the profile. [Profile Info] says:

 Recording started: Sat 17 Feb 2024 12:58
 Recording length: 1m12s 

So my profiling data don't show what happens between 12:44 to 12:58 :-(

Just for the sake of it, I'm attaching a pic of the first 10 seconds of the profile (at 12:58).

PS: Between 12:44 and 12:58 no FF window exists at all. Alt+Tab show no FF and in Task Manager I can't do any "Window" management, it is greyed out. I.e. no FF window exists for this process.

Question 1) What should I do to debug what happens between 12:44 and 12:58?

Question 2) How can it be that it takes 14 minutes to start FF from scratch (boot) while it starts quickly (~3 seconds) if it has been started once? I mean, all firefox.exe processes are gone when I exit FF, so starting FF again should be like starting from scratch, but apparently something is different.

Question 3) Is it normal that a FF, with only one tab (https://google.com/), run 12 processes in Task Manager?
