I am looking to Restore yesterday Firefox have lost all my pin tabs when I opened this morning the browser how can I get my old stuff back? Please help me out. Thanks

In Firefox's Task Manager, how do I know which tab is using which subframe(s) process?

For example, let's say I open Firefox and with only one single tab open, I open the following web page: https://audioplugin.deals/product/best-of-zampler-collection/

That page apparently includes content from several third-party websites because when I open it, Firefox's Task Manger shows processes for the following:

https://audioplugin.deals https://cloudflare.com https://google.com https://hcaptcha.com https://soundcloud.com https://stripe.com https://stripe.network https://stripecdn.com

The process for "https://audioplugin.deals" is the only process with a tab. All of the other processes are subframe(s) only, with no mention of which tab is using them.

With only one tab open, I intuitively know that all of these processes must be used by that one tab. But like most people, I browse using multiple tabs, and once you open multiple tabs, it becomes (as far as I can tell) impossible to determine which subframe(s) process is used by which tab. This makes it impossible to determine which tab is behaving improperly or erratically when there are issues (for example, when one of those subframe(s) processes is consuming an unreasonably large amount of memory or CPU cycles).

Using 148 on Debian trixie I do not see the option for "refresh browser"?

Does it still exist or is there an alternative ?

bold text''''bold text' In Settings under Startup, I have check to open all my previous tabs, but when I am shutting down, Firefox wants to close all my tabs before shutting down. If Firefox closes all my tabs on shutdown, then those tabs will not be there next time I start up .... how can I keep my tabs when I shutdown and have them next time I start up

Due to an internet outage, I got forcibly signed out of my Firefox account. I signed back in, but all my login info and passwords are just gone. I still have my browser history, and I'm even still logged in to some of my accounts, so I know some of my cookies and cache are intact.

Hi

I cannot reactivate spell check as I type, with English dictionary and the thick box ticked. Previously I could not get rid of spell check in my 2nd language (Turkish) but as I have managed, now I cannot restore spell check in English.

Can anyone help please?

Should I delete and reinstall Firefox? If I do will I lose my bookmarks?

Thanks in adance to all.

Can't enter text into body of post, ghosted (title allows me to type) on select sites (Kodi.tv). Changed to Chrome no issue. win10/64/FF 148

Strangeness... seem to be able to type post title, but not message body in all the forum threads. trying to post gives me an error and I am loggged in. Just re-installed Firefox.. no issues on other sites, the text body is ghosted... but not the title bar. At this point;  I'm locked out of messaging in the forum. (edited)

Installed Chrome and I'm back alive! Guess the new FFox is the issue? (edited)

I cannot access my xfinity account due to my anti-virus (Eset) blocking Firefox's access to assets.xfinity.com

I love Firefox and NEVER use Safari. I thought something had happened to my MacBook Air, stuck space bar or maybe even a virus? BUT the space bar issue doesn't occur when I use Safari. The issue is this: I will use Firefox (for everything). All of a sudden, the space bar becomes "engaged" and my text starts scooting across with spaces between it. I can hear it "stutter" a sharp sound each time it lurches along. I can then open up a word doc and the thing follows me there. Or when trying to close an unsaved word doc to prep for closing the computer. I restart the computer and to begin with, the spacebar issue is resolved but before long (sooner and sooner) it begins again to the point that I am restarting my computer now within about five minutes. I have uninstalled and re-installed Firefox to no avail. BUT, I can use other programs without problem as long as the problem hasn't already begun again, via Firefox. What on earth? I am now stuck using Safari... I have the most recent Firefox installed. I just re-installed the program a second time, yesterday. I don't want to open the program or I'll end up turning it off and on again and lose all of this but it was updated as of yesterday but I keep up on all the updates, all the time. It's been going on...about 4 weeks? But it started with occurring maybe once a week, then once a couple days now to the place it is multiple times to constant, during a day. I cannot use Firefox until this is resolved. Thank you for whatever help you can offer. I've run the diagnostic /first aid stuff to no avail through my utilities.

Hi, for about the last week (23 Feb 2026) when watching videos in my Firefox Browser, there are short stutters. First noticed in Youtube, so looked for updates to UBO and other extensions. Then noticed the same thing in BBC iPlayer and my4 streaming. It also happens when watching my media via Plex in the browser. It is not my network bandwidth or speed.

When I watch media via my Plex app or videos on VLC media player, there is no stutter.

I have included a link to logs recorded in Firefox profiler as suggested by someone on Reddit. firefox_profiler_2March26 https://share.firefox.dev/4b4moC0

I don't know if this is caused by a Firefox update, a Windows update. Laptop: Asus ROG Flow X16 (2023); Intel i9-13900H, Intel Irix Xe; NVIDIA RTX 4070 (mobile) Firefox 148.0 (64bit)

All drivers up-to-date. Please let me know if the link does not work - my first time trying to upload a link from profiler.

Thanks all.
