Firefox Форум

Need help figuring out why Firefox has a memory leak after an extended use of Firefox browsing. Don't know if its the result of an extension having this issue, or if its a Firefox bug. I have also provided my troubleshooting information, and a link to my memory usage is listed below for download: https://1drv.ms/u/s!ArspaZQCMwZ-iLU_CckOfLkl9DlETQ?e=MuIqsO Thanks in advance!

I did an Upgrade to a version of Firefox that would bypass those "Your Browser Is Not Supported" messages that apparently come from "Cloud-flare." I figured [naievely!] that my addons would "port" to the upgrade. They didn't. Is there any way [e.g., a putative backup file, perhaps] that would allow this?

Thanks in advance...!

Since upgrading to the last version, 125.0.3 I'm getting tab crashes. Is there any way to go to a previous version? I have not had any issues with the websites I'm visiting until this new version of Firefox.

I reset a computer, deleting all my files. I want to use, as I do elsewhere, Firefox as my browser. And though I signed into Firefox using my old credentials, none of my bookmarks are there. How do I complete this setup?

I've disabled all of my addons, cleared cache, and still youtube is broken for me. It works fine with Chrome still. Any ideas on how to fix? See attched screenshot.

I've been trying to connect to discord for a while, left it on for 2 hours and hasnt loaded. when i opened the console log, all it said was "Firefox can’t establish a connection to the server at wss://gateway.discord.gg/?encoding=json&v=9&compress=zlib-stream" all over. Please help.

Whenever I type in a website URL in the search-bar, first of all, the drop-down menu of related searches and websites does not show up. When I press enter to confirm that's where I want to go, nothing happens. The URL just kinda sits there, no loading circle or anything... Just a blank page. Only two of the icons on my toolbar works. The "Account" icon, which takes me to my Firefox settings. And my Extensions icon. Clicking the three little lines does nothing. The only websites i have been able to get to work at all are the settings page, and the Firefox troubleshooting page. I'm using Version 125.0.3, I tried using the browser both with and without hardware acceleration with results being unremarkably the same. I restarted Firefox and my computer multiple times to no avail, and the only thing I could find out of the ordinary was an error with Importing data from Microsoft Edge, which was not something I consciously wanted to do, but there was an error that popped up regarding that when i went to the settings page.

All that being said, I'm confused and at a loss for options, and could really use a Mozilla Staff member or someone who knows what they're doing to work me through this.

Firefox takes about 5 minutes to load every it launches, before working smoothly like it should. This problem occured first time yesterday morning, and I have no idea what could have caused it.

It happens :

• when I launch firefox normally (whatever the profile)
• when I launch it from the terminal (it provides no output at all)
• when I tell it to launch the Profile Manager (5 minutes to see the Profile Manager appear, then 5 more minutes to launch firefox using the selected profile)

It does not happen :

• when I click "New Window" inside an existing firefox process
• when I call `firefox --help` from the terminal

Here's what I've tried :

• First, I've seen pretty much every article from Mozilla Support, Reddit or SuperUser (writing this question is kind of my last resort)
• I've tried removing and then reinstalling Firefox from Flatpak, from the Fedora repos (using `sudo dnf install firefox`) and using the manual install via the archive (v125)
• I've tried downgrading firefox (when using the package manager install) from v125 to v124
• I've also tried the Firefox Developer Edition, same problem here
• I've tried using the "Refresh Firefox" feature and restarting in Troubleshoot Mode (both are also affected by the slow startup, which makes them particularly painful to execute)
• I've tried manually deleting the `~/.mozilla/` folder (= manually deleting my profiles)

When firefox launches, it does not freezes my OS and does not seem to use many system ressources : CPU usage is normal, RAM as well, and it does not seem to read many things from the disk as well (I've seen some threads where this was the issue).

And here is something interesting that I discovered :

• loading (including refreshing) `about:profiles` is also slow and this time freezes firefox (OS reports it as not responding, I can't switch tabs and I can't see my mouse). Other about pages seem to work fine (although I did not try them all)

Thanks !

PS : Even if I think it has nothing to do with the issue, I prefer to mention it here : I was messing with virtual machines yesterday when the issue occured for the first time. My disk got full at some point and I don't know but it might have messed with firefox. At this stage, I had not deleted any files that could relate somehow to Firefox, that's why I doubt it would have caused anything harmful to Firefox. (instead, I mounted an empty partition from my disk to get some space)

The increase happened here: /storage/permanent/chrome/idb/3870112724rsegmnoittet-es.files/

79 files taking 590MB created in 3 minutes, out of nowhere. Why were all these large files created?

I have used firefox for years as my browser with my home page set to google. I have always had a bookmarks toolbar but never a bookmarks side bar and do not want one. The other day a bookmarks side bar suddenly appeared. I have moved it from left side to right side and can delete it temporarily by using CTRL +B, but can't find a way to permanently remove it, i.e. make the default setting so that the side bar doesn't appear. can you help?

This is almost surely a "security" or "privacy" design, but it's an error. In Firefox - only (this works fine in Chrome) - if I open the LastPass Firefox Extension, find a Site, and Copy the password, then go directly to an open AnyDesk remote access connection, and Paste (or, lightning bolt menu, Insert from Clipboard), what gets pasted is a single wrong character, NOT the password that IS in the clipboard. (If I paste instead into e.g. a local Notepad window, the actual password gets pasted). I asked AnyDesk support about this, and they confirmed that it's something that Firefox is doing. It shouldn't. Copy is copy. Paste is paste. Why would Firefox do something so that copied text (which just happens to be a password from a password vault extension) pastes wrong when the destination just happens to be a remote desktop client (AnyDesk) to send the password through to complete a login at the remote end? Anyway, how to turn off this wrong behaviour? thank you. (Windows 11 Pro, 64-bit, 23H2, Firefox current - 125.something today, but this has been going on for some weeks at least, AnyDesk version 8 current)

Hello:

I have installed and enabled sync under the same Mozilla account on my desktop and laptop. The only thing that seems NOT to sync between them is my add-ons. There was no sync error log when I checked. I have already tried logging out and logging back into my Mozilla account on both computers, turning off my antivirus real-time protection, double-checking my sync settings, and restarting both my computers.

This issue is beyond frustrating. Does anybody have any additional suggestions to save my sanity by correcting this issue? I would appreciate any assistance that is provided! Thank you!

Respectfully, Jeffrey

May I first say that trying to get hold of you to make this report was painful, and took about 20 minutes and a long walk around Mozilla's assorted website, opening two accounts, etc.

I received a notice while using Firefox on PC that an update was available. I was going to put it off, as I had 25 tabs open, but the notice indicated that my open tabs would be restored once the update was complete, so I approved the update. It download and I assume installed the update, seemed to temporarily close Firefox, and then reopened the original page with all my open tabs, plus an empty page. When I tried to open the tabs shown, they all indicated that the tab had crashed and then gave me the option of restoring that tab or on some restoring all tabs. Neither worked, in fact, that Firefox page became completely unresponsive and would not allow me to browse new urls (the tabs just spun). I actually had to use MS Edge to get to anywhere to seek out someplace to make a report. I first went to the discussion group and opened up an account there, but from there noticed that feedback on Firefox was at a different url. I then needed to create an account "here". Since nothing was working, I closed and reopened the Firefox page with all the tabs on it, figuring maybe it would restore the crashed tabs. It did not and all tabs were lost. I can probably get back to some of them using the history archive, but it was very disappointing and will be even more time consuming. I am running the current version of Win 10 pro, 64 bit, on a PC. I thought you would want to know about this. Thank you for your time.

I deleted the old user names and passwords associated with my bank account. Now I can no longer login to my bank acct using Firefox. Only with another browser.

I tried to uninstall then reinstall Firefox but the problem continues. What to do now to login to my bank account?

Starting a couple of weeks ago, I began noticing that occasionally (every 2-3 days usually), a few empty files appear in my c:\ folder (Windows 10, as up-to-date as Windows ever is). They have names like "wal3A7109C6" (no file extension). Usually 4-5 will be generated at the same time (ie, same timestamp, so within the same second).

When I first noticed them, I (nervously) deleted a batch with no apparent consequences - but I had to activate Administrator privileges to get rid of them. I ran virus scans but have seen nothing unusual.

A few minutes ago, I had Firefox open but minimized to the task bar. I also happened to have c:\ open in a Window I could see. As I tapped to expand the browser, another of the files appeared, and the browser window behaved oddly for a moment, as though about to crash. The last few versions - I'm at 125.0.3 (64 bit) - have been crashing more than I'm accustomed to, but this is the first time I'd considered the browser to be a likely suspect.

Does anyone have any clues/possibilities to offer? It would be much appreciated.

Ok-So this popup window popped up when I returned to Firefox. I don't think it's legit and I am wondering how I go about blocking it permanently. I searched the settings but didn't see where I could post the URL so that is why I am posting this here.

I copied the URL but I don't want to post it here in case it could do something to someone else's system. But here is the screenshot. Please advise me what I need to do. Thank you! TGIF!

I am on a Mac running Sonoma.
