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.

Firefox freezes every few minutes for 10-15 seconds, even in Safe Mode. Task Manager shows one or two of firefox's sub-tasks as "Not responding" and CPU at 100%.

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.

we have installed Firefox 85.0.2 (esr). we are working in home office with a vpn connection (citrix gateway). the system is set to use proxy settings with a script - every time I start firefox new, it is set to "auto-detect proxy setting for this network" and I have no internet. Also with disabled vpn connection - i have to set the proxy setting to "no proxy" or "use system proxy settings" who sets the setting default to "auto-detect ..."? why is this not working in home-office

Every 2 to 3 days sometimes longer, Firefox will randomly reset itself and close out all windows and tabs to a single window and different search engine. Restore last session is never available when this happens even though I have that selected and checked and it does work when I manually close out windows and tabs myself so i know that preference is selected. My search engine preferences are always reset and have to restore defaults as well. Mac os Big Sur 11.2

Thanks to anyone who can help me solve this sudden mystery. Long time user of firefox on macbook pro and mac towers.

Every so often when I am browsing and go onto a website the text becomes all jumbled as if it can't read the font properly. This has only started happening recently. It definitely seems to be a font issue as when I copy the text and paste it into a document it reads perfectly and if I close the browser then open it again the text is back to normal. It seems to happen after I've been using the browser for a while.

I am using Firefox 85.0.2 (64-bit) on a Macbook running OS X 10.13.6.

This problem has been afflicting me for six months or so. On certain websites that open a new page in a new window, the new window instantly enters what I would describe as a "resizing loop": the window starts small and immediately maximizes. Each time it fills the screen, though, it immediately shrinks back down and starts again. This looping behavior continues endlessly, until I kill Firefox or somehow manage to get the malfunctioning window to close. On my employer's webmail, for instance, I'm not able to compose a new message, because it tries to open a new window and gets stuck.

The resizing is very fast and very incessant, fast enough to induce nausea in the unsuspecting user. Can anyone offer any suggestions?

Often when I do a search from the address bar, the search query is cut off at some point.

Say I want to search for "tofu quiche recipe", so I write "tofu quiche recipe" in the address bar and press Enter. This will often cause Firefox to search for "tofu quiche reci" or just "tofu qui". Even if the entered query, "tofu quiche recipe", is displayed in the address bar itself, it seems that the primary option in the drop down will have a certain delay in updating and say "tofu qui — Search with DuckDuckGo", and thus when Enter is pressed, Firefox will drop the last part of the query.

The issue doesn't happen when searching from the new tab page or directly from a search engine site, only from the address bar.

I installed Firefox on a MacBook Pro 13" (Mid 2012) with MacOS 10.15.7 Catalina. Before closing Firefox for the first time, I carefully opened settings and ticked "Restore previous session", under "Start" on the "General" settings page. But when I opened Firefox again, there were no tabs, just a "Welcome screen" as if it was the first time ever I use Firefox! This is extremely disappointing! I am really shocked! I had never thought that Firefox would screw me like this! I have been using Firefox on Windows and Ubuntu for many many years! I can add that it is Firefox 85.0.2. And now it updated itself to 86.0.

NFS mounted home directory caused a hang condition in firefox. Repeatable when creating ebay listing

I am using centos 8.2 with it's firefox 78.7.0esr (64-bit) I also have my home directory mounted via NFS using the automounter system.

In general firefox works fine in this configuration. However, when I get on Ebay and try creating a listing, firefox will hang when adding photos and/or moving the photo order. My NFS server will then start complaining about 'failed to contact remote rpcbind.

I try to close firefox and it doesn't It then will ask about a script running to long and offer to close. It won't I wait quite some time and it doesn't close About now the whole system is locked up and I may be able to get to the reboot menu I reboot and it won't because the process is hung. I usually have to power cycle to get things back.

I think if I waited for the automounter to time-out firefox may close at that time.

So the questions are: Is this supposed to work in an NFS environment? What is going on to cause the hang? Are there environment variables to move "some directory" to the local disk drive if that is the problem?

I sure hope someone can answer this for me. Thanks Warren

Hello. After updating Firefox on my Macbook, a website I visit now will not load, the message "transferring data" will appear and the status indicator looks like the data is loading, then when the status bar looks like its at 100%, it will start over and show "transferring data" again, and this keeps repeating indefinitely. This only happens when using an IPv6 address, it works fine with IPv4. This did not occur in Firefox 81.0.2. This also does not occur on other websites or with other browsers. I am looking at the notes for releases between 81.0.2 and 85.0.1 but am not sure what may have changed that would cause this. The website in question is a BMC GUI for a server I'm working on. If anyone has any ideas I'd really appreciate it. I tried the debugger in Firefox but not sure what I am looking for. I did set a breakpoint for caught exceptions, and the screenshot is attached if it helps any... Thanks!

I have noticed in my options section that I can specifically pick what I want. But, looking at it from a computer performance point of view (computer speed) which settings are best? In the browsing category what should I select? There are more than a few options there. Which ones do I need for good computer performance? And which ones should be not used? In the applications category what selections should I pick? There are currently many-many selections there. Are all of them needed or required? Would it be advantages to remove some? Hopefully someone can help? Thank you.
