My Firefox crashed and one of my windows with a bunch of tabs was lost. I have a bunch of windows open for dedicated sorting of tabs (one for socials, one for videos, etc). Earlier, my Firefox crashed and it attempted to restore my session but did not restore one specific window I had. I looked in the "History > Recently Closed Windows" and it was not there either. This specific window had a bunch of work related things on it and while I can sift through my history and re-open each tab individually and rebuild it that way, that's really frustrating and time consuming. Is my window just lost now?

As the title says, with both with https and http firefox displays this warning:

But no way to bypass it, trying to login to my ubiquiti edgerouter at http://192.168.1.1 or https://192.168.1.1

What can i do?

For some reason firefox uninstalled on my computer, I genuinely do not know why. When reinstalling it, I have an old save from my backup of that morning (I have it setup that way). However, I do not remember this password whatsoever and I am freaking out a little bit since I have information on there and I am just trying to get it restored onto my account.

Any help would be appreciated.

Sometimes a search term will pull up many emails I need to sift though, like in the case where it's a common word, like permit. I was searching the term "permit" for building permit emails and got many unrelated emails that were more recent with permit in the email body. I am able to quickly skim and see these are unrelated but the limiting factor is only ten results per page. When I click load more, takes a few moments to load. I was unable to find any way to change this. How can it be done? Should be possible, it's doesn't affect Mozilla's processing because everything is done locally on my machine. I would much rather 100 results to load or to load indefinitely.

Additional question: on that search term, many unrelated emails came up as mentioned before. When I searched the same term in gmail in my internet browser, only relevant emails came up. Why is this? How do I improve the thunderbird search?

Video are stuttering when I play on YouTube.com as well as on streaming websites. I have used firefox beta to modify "layout.frame_rate" and "layout.throttled_frame_rate" to 60. My phone is Motorola's Signature. Video is working for now but please look into it and fix this permanently.

When I download with this browser, I cannot open the file and it states download has "failed". Any other browser I use allows me to open the file. I use Firefox most often because I like the way it performs, but the download issue causes me to look elsewhere for a viable browser. I cannot seem to find what is causing the download failure and am hoping you can offer a reason that will provide a fairly quick fix.

Some websites' signin/signout pulldown now impossible to identify and access, because only bottom half of the Tabs field displays. Top half is always obscured by a white bar (see blue arrow in attached JPG screenshot).

i am running Firefox on a Windows 10 Dell G3 laptop. I wonder if this is a problem with settings or with Add-Ons?

Hello,

I have some keywords linked to some searches saved as bookmarks - image attached as an example.

I have noticed that the keywords are no longer working in my URL bar. I am using Firefox Developer Edition, and I think the keywords have stopped working since version 153 was released.

The keywords on the proper search engines are still working.

Has anyone else observed this?

Thanks

Hello community,

I've been moved to MacOS at work and since then, Firefox will not always restore my pinned sites when I start it the next day.

Here is what I do:

1. Right click a tab, select "Pin Tab"
2. Go about my day
3. At the end of the day, I close Firefox by using command Q and shutdown my Mac
4. The next day, I start Firefox and most of the time, my pins are gone

I did not have this issue on Windows Firefox. I am using MacOS 26.5.2 and Firefox 152.0.4 Firefox says "Your browser is being managed by your organization" in settings. It is a link that can be clicked and the only active policy showing there is "DisableAppUpdate" which I assume is because we have our own tool to manage software updates.

Any idea what could cause my pinned tabs to disappear? I did not really customize the settings so far, I do NOT clear browsing data when exiting FF and the startup option "Open previous windows and tabs" is NOT selected. I have Ecosia and 1Password as plugins.

Any help appreciated, thank you.

I'm using Firefox from the official Ubuntu repository (packages.mozilla.org). I have used the (very cool) "translate page" feature successfully, but for some reason it doesn't seem to work on https://wiki.openstreetmap.org/wiki/NL:Basisregistratie_Adressen_en_Gebouwen which I'd like translated to English. Even though Firefox thinks the page was translated, only one of the headings seems to be in English.

I would like to understand how to troubleshoot this and help you improve this great feature. Thank you in advance.

After Thunderbird 152.0.1 Windows x64 lost its mind:

* my main calendar
* not allow recreation from backup data
* would not load profile

I had no option but to remove and reinstall.

Local Folders has 4 non-removeable folders Drafts - XXxxxx, Sent, Trash and Outbox that were not there in the past 20 years.

Sometimes, for no apparent reason, on my Win 11 ASUS laptop, Firefox will suddenly use a lot of resources, such that the temperature jumps from about 50 degrees to 95 degrees and the fan runs full speed. It appears the only way to stop it, is to close FF then reopen. What might cause that?

I also have an unanswered previous question about being unable to pay accounts.

Cheers, Keith

I’m using the latest stable Firefox package from the official Mozilla repository for Ubuntu, on a system with 32GB of RAM.

I’m also using Microsoft Teams for work calls, in the browser (because Linux) and I notice that Ubuntu has killed the FF process twice last week because it was using too much memory - see attached image. I’ve only had 4 or 5 Teams calls last week so this isn’t a great success rate. It seems that after half an hour or so, FF has hogged so much memory that the OS feels the need to kill it.

If this is a known issue: are there any known workarounds?

If this is not a known issue :Can I help by providing troubleshooting data? How?

Thanks in advance!

Logging in to Twitter/X is no longer possible as of a couple of days ago. After entering the username, pressing the "Next" button does nothing. Using the Desktop or Mobile version of the site makes no difference.
