Using previous advice found for this problem here, I typed the following into Terminal. The results show I have three profiles, which I'll try to explain below.

cd ~/Library/Application\ Support/Firefox/Profiles/
ls -l

drwx------@ 41 abababab staff 1312 Jan 15 13:38 0kr25gzy.default-release drwx------@ 71 abababab staff 2272 Jan 15 13:20 8638osoq.default-1513387167461 drwx------@ 37 abababab staff 1184 Jan 16 13:57 k8u9jknd.default-release-1

I use Firefox as my business email and all was working fine until I upgraded Firefox using my Safari browser and created another login profile based on my personal email. That's when the error 'a copy is already open' began. To solve it, I did the above and had two profiles a 'default' and a 'default-release'. I believe I deleted the 'default', and the problem remained. Then I tried a reinstall, and I suppose that's the 'default-release-1' profile, but I really have no idea. The problem for me is that I need to import bookmarks, the business email account linked to Firefox and Host Gator, and all my LinkedIn, MailerLite stuff. I do not want to lose all this and just do a clean reinstall. However, now because I can't open any version of Firefox, I have no way to access the business emails, etc, so I can't recover the Firefox account linked to this business email and get all this stuff back. And I don't know which of the above three profiles I need to delete to get it all working again. Please help!!!

Firefox (84.0.2 x64) has recently become a memory hog to the point where my system (W7) slows to a point where it is unusable. I do not wish to spend an entire day (or more) troubleshooting in the hope that I can make go away a problem that didn't exist 1 month ago do so how can I roll back to an earlier release (say the one running in december last year) which did not have any of these problems?

I attach two screen prints from a laptop (W7 12GBRam) running one instance of firefox with maybe 20 open tabs Windows Task Mgr which shows Firefox with 9 processes using around 5GB with one process using 2GB Firefox task mgr which shows 25 tabs using a total of around 0.5GB

Clearly the info in the firefox taskmgr is rubbish - or rather not reporting the same thing!

I have used Roboform password manager with FF for years. Within the last 6 months, Roboform's toolbar no longer automatically displays below FF when I open FF. I have to force it to by going into RF options and dragging the RF icon onto FF (see attached screen shot). As shown in the image, RF and/or FF doesn't even think RF is installed! But it is. I've contacted RF multiple times, and they claim they're working on it. I wonder if anyone in the FF community has the same problem. Thanks for any help. Steve

Pocket 'View List' stopped working in Firefox

I've been using pocket daily for a long time, and just recently the 'View List' feature (i.e. view the pocket website page with my saved links) stopped working in Firefox. That is accessed in the normal way using the Pocket icon in the address bar, or with the link: https://app.getpocket.com/ - they both go to the same address.

When that Pocket 'View List' page is accessed, it gives all indications of having loaded fine, but all that shows is a completely blank white page with the horizontal line and faintly greyer section at the top of the page, and absolutely nothing else.

Firefox version: 78.6.1esr

I'm pretty sure this was broken on a recent update (of Firefox). I'm also pretty sure many other things were broken in Firefox by recent updates - never had Firefox so damaged by an update before - things like on Amazon website pages (to pick something well known), product images randomly don't load (refreshing gets them to load), pages randomly display garbage (refreshing brings them back), etc, pages load fast but elements on page are not active (can't be clicked) for several seconds on complicated pages like an Amazon product page - never had this happen before recent Firefox update - I don't know if this is all related, but it feels like it is (and that Firefox has been broken in many ways only recently).

All these things, including viewing the pocket list, still work fine in Chrome.

Anyone have the post issue in Firefox? Or the other issues just recently? Is there a fix for this?

Thanks

Long time Firefox user here - been on from the start (about 2005), and don't want to switch because I love some features like the Panorama View extension, Context Search extension etc, and it's always been a great browser.

Recently though (not sure if it's just recently, or I've only just noticed), it's so slow. I tried a brand new profile, no extensions, no settings changes, and it's the same. Example loading times:

bbc.co.uk/news Firefox: 14s Edge: 2s chess.com Firefox: 19s Edge: 4s chess.com play vs computer Firefox 38s Edge 2s

https://youtu.be/er9jBysL0vEFirefox vs Edge (YouTube)

So it's not my profile settings or extensions.

BUT, I tried it on a different user profile on the same computer (Switch User from the Windows Start menu), and it's fast!

Why is this, and what do I need to do on my user account to speed Firefox up (keeping my same Firefox profile)?

Thanks in advance.

Hello, I have problem with YouTube. When I am clicking "Share" button I got screen with infinite loading. The same issue happens when I want to open menu by clicking on my avatar. On dev console I am getting a POST error: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/401

I tried to: - clean Google/youtube cookies and stored cache; - clean then all cookies; - relaunch Firefox with all addons disabled; - enter via private mode with/without addons; - flush dns on dev console; - disable completely antivirus; - change DNS.

What is interesting, that problem happens only when I am logged in to my Google (YouTube) account and only on Firefox. Even on private mode it works until I do not log in to my account.

I would be very grateful for help.

When Facebook updated their system a few months ago, running it on firefox with windows 10 on a pc crashes mozilla. It happens if you are logged into FB for some length of time (say an hour). I have no extensions operating just plain firefox. I turned on task manager inside firefox to watch what happened over time along with windows task manager. Within a half hour, FB is using high energy impact and just about all available memory in the system and filled the cache as well. Eventually it just freezes firefox and I have to kill the program go back and clear the cache and often do a complete refresh of firefox

It's been a while since I noticed Firefox video is laggy on every website. I thought it was about some driver problem but everything else seemed to work well. I downloaded Chrome and it didn't have any problem running any video.

I tried clearing Firefox's cache and I tried to "refresh Firefox" on about::config, but it didn't work. I don't have any missing system updates, I'm running Firefox 84.0.2-1.fc33 on Fedora Workstation 33.

I don't like using Chrome so your help will be really appreciated.

Thanks in advance!

Pretty much title.

Since about two weeks when I open firefox the browser freezes every few minutes for 10-15 seconds. Launching firefox in Safe Mode or disabling all extensions didn't help. When I open Task Manager during freezes it shows that Firefox is "Not responding" and when I open sub-tasks it's usually one or two causing the problem. When I close those either firefox closes completely or youtube or reddit crashes, leading me to believe it's something with those sites? Refreshing or reinstalling firefox hasn't helped. I'm on Windows 10 (all updates installed) and Firefox 84.0.1 (x64) as of the time writing this.

I hope someone can help and suggest something. I would hate to switch to another browser, but the problem has become unbearable.
