I accidentally typed my protonmail password into the field of my username/mail address. I don't remember what more I did (propably answered yes to save) but now there is as autofilled my password for username always I open my Protonmail account. I am using Firefox as browser (should be the newest version) while Emailing.

I tried to delete autofill of Firefox according to the next advise: "go to Settings > Privacy & Security, scroll to "Forms and Autofill," and uncheck "Autofill addresses" to stop saving them"

Then I was astonished. There is no "Forms and Autofill" setting on my Firefox at all!

Protonmail settings didn't help either nor Windows 11 - neither FAQ.

I run Firefox on Fedora Linux (Silverblue). For several releases I've noticed that the reader mode only displays the Close Reader View, Text and Layout, and Theme options and nothing else i.e. no content.

When I run it in troubleshooting mode, it works. I've tried disabling all my extensions, deleting all my extensions,restoring the browser to default settings but nothing makes a difference. I'm always on the latest release (currently 147.0.3). I currently have multiple profiles, but it didn't work even before I rebuilt them. I'm out of ideas.

Any help is appreciated

The website commonly used by Arizonans to make filings for court, will not work properly with Firefox, even after turning off Enhanced Tracking Protection. I had to use Chrome instead.

I moved and my moving company had my computer soundly packed in a box. After 2 months I have hooked it up. Tried to open my Firefox and the message stated the file is corrupt. I've opened a new Firefox account. Can I get my old account back or can I get my old information into my new account?

Environment - OS: Omarchy - File manager: Nautilus (running as --gapplication-service) - Desktop portals: xdg-desktop-portal + xdg-desktop-portal-hyprland (+ gtk fallback) Firefox: latest stable from Arch repositories

Observations Only one Firefox process is running (pgrep -a firefox). Only one Nautilus process is running, but it receives two open requests, resulting in two windows. The issue does not occur in Chromium/Chrome, which opens only one window. Running xdg-open <file> manually opens one Nautilus window.

Portal logs show GTK being chosen as last-resort fallback, but system-wide XDG configuration appears correct.

Question

Is this a known Wayland/portal bug in Firefox? Are there recommended debugging flags or patches to trace the duplicate launch request?

Hello everyone,

I’m experiencing ongoing problems with Firefox and hope to get some help or clarification here.

Main issue: I’m unable to sign in to my Outlook / Microsoft email account using Firefox. The login page does not load correctly, or the sign-in simply fails (Error 400). When I use another browser (for example Microsoft Edge), the login works without any issues.

System information:

Operating System: Windows 10 IoT Enterprise 2021 (LTSC, supported until 2032)

Firefox version: 147.0.3 (64-Bit)

Additional problems: Besides the Outlook login issue, Firefox has recently become more problematic during normal daily use:

Text selection with the mouse often does not work correctly

Clicking and dragging to highlight text is unreliable or stops working

Pages sometimes feel unresponsive, (ChatGPT)

Overall, the browser feels less stable than older Versions on Windows 10 22H2

These issues seem to be getting more frequent over time and occur on multiple websites, not just Outlook.

I switched my system to Windows 10 IoT Enterprise 2021 (LTSC, supported until 2032) in the hope of improved performance and stability.

What I have already tried:

Clearing cache and cookies

Disabling all add-ons/extensions

Testing in Private Browsing mode

Restarting Firefox

Unfortunately, none of these steps resolved the problems permanently.

My questions:

Is Firefox fully supported on Windows 10 IoT Enterprise 2021 / LTSC for the long term (until 2032)?

Are there known issues with Microsoft / Outlook sign-in specifically in Firefox?

Are there known stability issues (text selection, mouse interaction, page responsiveness) in recent Firefox versions?

What settings or troubleshooting steps are recommended to improve stability?

Thank you very much for your time and support.

Best regards, Marco Klecker

Within the Applications section of my settings, I have it set to open content type of crcc with an application. However when I try now after the latest Firefox update, it opens a new blank tab instead of just launching the application. The URL of the blank page is just "crcc://the_URL_of_the_launching_site?params=dG9rZW49ZWJlN2IyY2FmMTM3YmQxODM3ODZhZDU1NWY2Zjc0ZDNiMWE5ZWIyMSZ2ZXJzaW9uPTEwLjMuNTEzMjEuMjUxMjAmdHVyblBhcmFtcz0lMjJzdHVuJTNBc3R1bi5sLmdvb2dsZS5jb20lM0ExOTMwMiUyMiUyQyUyMnN0dW4lM0ExOC4xOTYuMTA3LjIwOCUzQTM0NzglMjIlMkMlMjJ0dXJuJTNBMTguMTk2LjEwNy4yMDgrJTVCMTc3MDk5NzE1MSU3Q2JsR2hXNDQ3STV5NVl1ViUyQlZ0WXBtMmdKUkpjJTNEJTVEJTIyJTJDJTIyc3R1biUzQTE4LjIwOC4yMy40NSUzQTM0NzglMjIlMkMlMjJ0dXJuJTNBMTguMjA4LjIzLjQ1KyU1QjE3NzA5OTcxNTElN0NibEdoVzQ0N0k1eTVZdVYlMkJWdFlwbTJnSlJKYyUzRCU1RCUyMg==" I tried the standard clearing cache, private window with no help. Anyone else notice this and is there a work around. Of note, after about 5 minutes it does eventually open the application.

Hi, I use Firefox as a primary browser on multiple PCs, so want it to remember a couple of addresses & payment methods for easy daily useage. However, I also access one business domain & when using that website only, I don't want Firefox to offer/remember/anything when it comes to addresses (which will be customer addresses) or payment details (again, for customers). Other autofill, like suggestions for some form fields would ideally still work.

Is there are way to make one domain exempt from address & payment saving/retrieval?

Thanks.

I want youtube to go back to the list of websites on the url drop down menu. I'm annoyed that Heroforge replaced it after only two visits to the website and I don't know why it even did that.

how do you disable or unreaveal when the mouse hovers over the task bar (search bar) at the top while in full screen mode (f-11) to me this annoying when the mouse enters that section of the screen. chrome does not do this. Is there a way to toggle off a switch in a setting? if not, can one be added.

When Firefox updated to 147.0.3, it shredded Quick Dial and I am using the latest version.. Less than half of my tabs still exist, and many of the "everyday" tabs - banking, utilities, online purchasing, etc, - are simply gone. Unless there is a solution, and I have contacted the developer with no success, I will no longer be a Firefox user. Beyond this issue, Firefox has been increasing difficult to use for purchases (big examples, Rock Auto, PayPal) and have had to switch browsers too many times to complete purchases DESPITE making exceptions for these websites in Settings. This situation is the proverbial "last straw". Solution or I'm out. Screenshot attached would have originally shown A FULL PAGE OF TABS.

Starting about a week or two ago, I noticed the text of Firefox is grainy. But when the cursor moved, it would get grainy in a different way. So, some letters which were previously unreadable became readable, but other letters became unreadable.

Going to the same web pages with other browsers renders the page readable. So, the problem seems to be Firefox specific.

Even while typing this, portions of the characters on my screen blink in and out.

If there is no solution, I will have to utilize some other browser.

Thank you,

i do use ad blockers "experiencing problems find out why "well,of course lol. I know this ,but when i shut down the browser & re launch the browser it won't initiate/execute. not matter what I do. I then run the DISM script and she (firefox) fires back up again. Any insight or work around to fix this this nagging problem would be greatly appreciated. Yeah, windows 11, 32 gig of ram, 60 mps down 75 up.

I appear to have my bookmarks duplicated. Bookmark Menu list of bookmarks, bookmark 1

                                                           bookmark 2
                                                           bookmark 3 etc
                                                           ........
                                                           bookmark 1
                                                           bookmark 2
                                                           bookmark 3 etc

At a glance, the repeated bookmarks are the same, but I could have filed a new bookmark in either set. What can I do to stop these duplicates?
