When I want to view passwords Firefox is asking windows credentials which I don't have. Now I can't get access. It used to ask for my Firefox password what happened.

I have been having trouble with my Windows 11 laptop. In my efforts to resolve these issues I noticed that I now have two installs of Firefox in my Control Panel. Both installed during my time of dealing with my Windows issue. Five days apart Feb 5 and 10, 2026. Both show the same version number 147.0.3, and same size 322MB. I have used FF for many years so these seem to have been installed sometime during my efforts to repair Windows. My FF was never a part of the Windows issue AFAIK.

Anyway I have FF working as I like with my Session Manager and various AddOns and personal settings, so I do not want to have to start over with FF. So how do I choose which instance of FF to uninstall in Control Panel?

My issue with Windows was my Outlook would not connect to the server. I assume Microsoft Exchange server, my internet connectivity was fine. And FF was fne as well. I eventually was able to repair my M365 connectivity. Major PITA from out of nowhere.

I don't know where this should go so if you can foward it on, please do so.

When I delete an email, a pop up gives me a chance to compact folders now, or remind me later. This is a minor annoyance and can probably use a fix. I do want to compact folders, but not while I'm in the middle of reading and deleting my email.

How about using whatever trigger is used to, instead of popping up the small window, do a delay and open the popup when it's more convenient and useful, like when I delete my trash or go to close the program?

I’m using Thunderbird 148, IMAP, and my folder pane folder mode is set to All Folders. I seem to remember Thunderbird showed me a quota bar so I would know how much space was left on the server. Recently no quota bar has been visible, what gives?

I can submit posts on X using Chrome, but Firefox, for some reason, has cut off the portion of the posting box that contains the submit button and other edit features. It simply vanished as of March 10 2026.

I have attached screenshots showing FireFox vs Chrome.

I cleared cache and cookies to no avail. I have the latest Firefox version. 148.0 64 bit. Windows 11 operating system.

• OS Version: Microsoft Windows 10 Professional (x64) Version 22H2 (build 19045.6466) • Firefox 149.0 (64-bit) • Thunderbird 140.8.1esr (64-bit)

Have NO idea "which topic best describes my question" from your drop-down list (above), so simply clicked on one.

Restarted my PC; all of my bookmarks disappeared. NOT acceptable. (Or is this just another "improvement" from Firefox . . . ?)

Where did they go; how do I retrieve them?

Really don't want to wait days until there's a response, as I DO USE MY BOOKMARKS ALL OF THE TIME.

Thank you.

Thank you for your help and answer. I hope I can continue writing to you in German as well?

I can't find a contact person and the name of my Mozilla account has been changed; is that normal?

Question: A number appeared after my email address, so "email" and "1954". Who is that? Is that normal?

Question: Thunderbird Developer Toolbox: Can you see in the program? Can you see my emails?

Question: Are there any Thunderbird users left who speak German?

Questions: Thunderbird Portable The archive option isn't updating? How long does the backup take?

Different Thunderbird versions display a programmed year date in the archive option. For example, 2021 in one version and 2024 in another. Is that normal? I can't change anything.

It's as if it's accessing some kind of backup and maybe even sharing it, and I don't know what's correct.

Question: Update Channel Ellipse Update Channel esr. Previously, there were different channels. Isn't another channel better? I've read that it's more stable than switching. Is that true? Information regarding the question below?

You are currently on the esr update channel. I'm experiencing stability issues with this one.

AirTable.com online app attached documents are downloading when selected to view. Not a problem in 148. Not happening on other browsers.

Sometimes I need to open XML files on my PC or in a network folder. If I open the file in the first tab in Firefox, it displays a neat and formatted rendering that makes it easier to read. However, if I open yet another tab, it displays a sequential text file that's difficult to read. How can I apply the style of the first tab to all open tabs? I've attached explanatory images (I hope). The second image shows how I'd like the XML file to always be displayed, regardless of the tab's position. Firefox 149.0.2 on windows 11

You say to go to the download page and my version of Windows will be detected & you'll give me the correct version. However, IE 8 in Windows 7 won't go to your download page. So, I need to download from another computer and copy the file to the Windows 7 computer. This doesn't work when you detect that the computer doing the download is a newer computer. How do I tell your system to give me the Windows 7 installer?

When I've had trouble signing-in to a commercial website, it often says, "Clear your cache." But in Firefox settings, it looks like clearing it will cause my frequently-used passwords to disappear. Am I reading that correctly? If it's true, how can I clear my cache without losing "remembered" passwords and other log-in information?

I'm not very tech-savvy, so need instructions in very plain, "for dummies" English. Thank you for any help.

re: OAuth2 Authentication for Yahoo, AOL and ATT

My settings selections don't really follow your help descriptions to the letter,so..., also, I already have 2 accounts on 2 platforms and they seem to already be configured with SMTP outging servers using OAuth2.

I'm confused since I'm now on 140.8.0 and have not needed to change a thing, contrary to expectations set from T-bird app popup warning and Mozilla article.(?)

I used to be able to have all sorts of tabs open for an entire month. Now, I can't keep them open even for a day. It seems to be a problem selective to Youtube (other tabs like Yahoo Mail still work), leaving my Alienware 15R4 laptop fans running really loudly for a few days now, since updates ran (not sure if that's related), and leaving me having to shut down and reboot the browser, daily, instead of once or twice a month. Is there anyone working on getting us back the old Youtube, or replacing Youtube with something like what it used to be? I am running adblock plus and uBlock Origin, should probably turn them off to see if they're related to the problem, huh? I'd hate to start having to use a different browser.

I tried transferring TB to new computer, nothing has worked. w11 TB148. Manually didn't work, tried coping from Troubleshooting Information/profiles. I don't know why there are 2 TB's? Under local and roaming but I tried. The video is out of date. It's a new install of TB so it opens with create account, both computers W11 and TG148! Please somebody tell me what I'm doing wrong? Thanks.

Somewhere between TB 15 and TB 115 (my current), we lost the TB information page which included a link to the profile. Is there some current replacement for that capability? (I'm having a profile problem and would like to see how that looks to TB.)
