Subject says it all, but it seems to occur with any site, anytime I try to open more than three or four tabs (ctrl-clicking links on a forum, for example) my Firefox instance grinds to a halt and starts consuming most of my CPU (Ryzen 5 3600).

I've tried turning off Firefox's various protections. I tried troubleshooting (formerly "safe") mode, and the problem isn't as bad but is still present as far as I can tell. The only extension I can think that would be making it worse is Tree Style Tab, but I don't know enough about interpreting Firefox profiles to verify.

The only reason I consider this odd is because doing the same thing in Chrome doesn't have this issue on this same device. If I open many tabs quickly, Chrome itself is still responsive. Those newly opened tabs may take a while to load and become interactive, but it doesn't affect the rest of the application. I pay my ISP for gigabit DSL, and as far as I can tell that is roughly what I get. In my case, Firefox doesn't behave this way.

Any method I open a new tab, it always takes up to 7s to load, while completely suspending my browser. This also happens in troubleshoot mode but not in incognito. Directly opening websites in a new tab doesn't trigger that bug. I don't recall when this started to happen, it might be after some new Windows update.

I have included screenshots from Firefox Profiler, both from regular window and incognito one.

It worked nicely for many years, until today. I installed Supraland from Steam, played for a couple of hours, and suddenly my Youtube page went glitchy - not the layout but minor elements were getting scrambled, especially text. I'll attach a couple of pictures to show it. In fact, all pages glitch if their content changes even a little. As of typing now, I see the glitches, with a word or another getting butchered. Gifs and videos are full of that.

Windows 10, the current update, Radeon RX 580, the recommended AMD drivers installed (and reinstalled again and again, 23.11.1)

I think I did pretty much everything with Firefox. Disabling hardware acceleration fixes it (but then of course the browser goes slow). Games work fine, including Talos Principle 2 which is intense enough. The clean install, reinstall and all that. I'm writing from the beta stable build now. I've tried to regress to the previous versions too.

It strictly coincides with the game installation but I have no close backups - who knew that some game might just do that. Then, of course, I tried to uninstall it too.

Thoughts?

Добрый день! Почему не меняется язык на английский? Как его сменить?! Только не надо мне писать про удаление кук и чистку кэша! Я только что это сделала потому что не работал чёртов логин в чёртов акканут чёртова твича!

After updating to Beta 122.0b3 (64-bit), the active tab is now highlighted with a simple white outline instead of the coloring surrounding the address bar. My selected theme has not changed, and the same goes for all of my extensions. I could not find this change in the 122.0b Release Notes.

If this behavior is intentional, is there any option to return to the previous behavior (including in about:config)?

When selecting "Open in Firefox" in the "What do you want to do with this file?" box or on about:preferences and then opening a PDF file on the web, instead of downloading the file to RAM and opening it with its online address, Firefox downloads the PDF to /tmp/mozilla_${USER}0 and opens it from there. This also adds it to the download history. I have set the about:config flag browser.download.start_downloads_in_tmp_dir to true so the files I just open and don't want to permanently download don't clutter my $HOME/Hämtningar (downloads) folder. I tried to first prevent that by selecting the default action to do when tasked to open a PDF, but that didn't fix it, so I set the about:config flag. Unfortunately, setting the default action stopped Firefox from opening a PDF inline without downloading it and I cannot find any option along the lines of "Preview in Firefox" (as described in this support article ).

My Firefox account and associated passwords were left open on another notebook. I have now changed my Firefox sync login password from a different PC and signed out of other devices. Can a user on the previous PC sign in with a password that is saved in Firefox?

Is there any way to rotate between different screen sizes option using shortcuts keymaps which appear during "responsive design mode" is on. I found extensions which resizes whole browser & they helps. but it also causes developer tool to resize along with browser which hinders me to see different css properties. so i am looking for a way to rotate only screens.

"Responsive Design mode" is what turns on when we press ctrl+shift+m.

I Love using firefox more than Chrome. This is my go to browser.

When I try to log into my website - https://huppbrian.us/tsc-admin - with Firefox Developer 111.0b8 (64-bit), get the following error first time every time... Error: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress. If I try again without making any changes, I'm able to log in fine. I've tried playing with the protections settings, but haven't found the magic pill to fix this yet.

Steps to reproduce:

1. Have Google as the default search engine.

2. Type a search string into the address bar.

3. The address bar briefly shows a URL for the Google Search results.

4. The address bar is very quickly overwritten with the original search string.

See screenshot for example.

How do I stop step #4 happening? I want the URL to remain in the address bar, for example to be able to give somebody a link which executes the google search.

I think this is new in FF121.

I am on Firefox Developer Edition 120.0b9 (64-bit macOS). Using sites like whatismyip and whatismyipaddress, I am seeing that I have a VPN or Proxy enabled. When I use Chrome, I don't see this. I went through all the settings and turned off anything that could even remotely be related, and still get the same results. Does Firefox have a built in VPN that I am unaware of? Is there a way to turn it off?

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

Took me a long time to nail this issue down. Recently (past 1-2 years?), Firefox has started suggesting the base website when you have bookmarks that include the base domain - and it's really bothersome from a UX perspective. E.g. if i have "adobe.com/express" or any other adobe bookmarks, the FIRST autocompleted url Firefox gives me is "adobe.com" which I DO NOT have as a bookmark. In my Firefox settings I also have Shortcuts and other search suggestions disabled.

Why is Firefox doing this?

When I bring up Google Maps I put the address in and Firefox shows an error message. This has been happening for a couple of months. See Error Message below.. Google Chrome has NO problem pulling up the address. How can I fix this? Thank you.

I developed a web app that checks the existing session login for each new page. So, after logging in the first time, the user is shown a dashboard with a list of functions they can access (My Account, etc). When an item is clicked and the application calls the function, it first checks for the existence of login session. If it's not there, then the user is forced back to login screen. However Firefox is deleting the session at some point so when the session is checked for the new function, the user is forced to login again. Chrome, Safari, Edge do not and are fine.

Enhanced tracking is turned off for the site and is shown as an exception. What is happening and how can prevent it?

I am attempting to build a script (extension) that will open any focused page in Firefox with Microsoft Edge from the context menu. The intention is to utilise the existing microsoft-edge URL Protocol in Windows instead of a native client.

QUESTION WILL MOVE TO https://discourse.mozilla.org/

I'm running Firefox Dev edition and I cannot get it to load any pages except for Mozilla pages. I have tried all the fixes suggested there and it still refuses to connect. I'm at my wits end. Any hail mary optoins or do I have to reinstall and start again?
