Firefox Community Forum

I run the current Firefox version under Windows 11 Pro on a Dell Inspiron 15 3530 laptop, Lately, I've been having problems with my bookmarks:

• First, I found that I had somehow lost a large number of bookmark tags; it took me several days to restore them,
• Next, I found that I had lost a bunch of bookmark subfolders; the bookmarks (for the most part) are still listed under their tags.
• When I try searching for tags in Bookmarks Manager, the search yield no results
• When I try to restore my bookmarks from a previous date, I get an "unable to process file" message.
• When I try to open the profile folder through the debugging information page, I get a "file not found" message. After some searching, I found the profile folder not at "C:\Users\croge\AppData\Roaming\Mozilla\Firefox\Profiles\7csymh5k.default-release", but at "C:\Users\croge\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles", Something seems to have gone haywire--did I miss something, or is there an error somewhere?

I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com

The lack of a title bar makes it impossible, for example, to close the application by pressing the "X" icon in the upper right corner. The title bar does not appear when the application starts, but does appear when the application window is minimized and then maximized.

When I opened Firefox[^1] today I was greeted with a "Donate to Mozilla Foundation" page open, with the message:

"You power Firefox. Now donate to make good tech the default.

Mozilla Foundation — the non-profit behind Firefox — is building a future where technology serves people, not power.

Your donation to Mozilla Foundation keeps the internet open, private, and built for people. Donate today to make good on the promise of the internet."

Does this message mean that Donations to the Mozilla Foundation now fund Firefox development? As I understand it, previously donations were not allowed to be used by the Mozilla Corporation, which actually develops Firefox. I'd love to donate to fund Firefox development, as I feel it is a critically important open source project.

[^1]: 145.0.2 from the Mozilla Debian repository.

When i try to insert a screenshot through the clipboard on google or yandex image search, the original image is corrupted. Even i try to upload an image via classic upload-button the same problem reproduise. On other sites there is no similar problem, as well as trying to insert the same image but inside the application windows.

In attachement: yandex/google and default image i was trying to upload.

I have Firefox set to use the built-in .pdf viewer to avoid Adobe's intrusive AI features. I have disabled Adobe's AI features in the Acrobat settings, that does not seem to apply when Firefox opens the Acrobat reader. Consequently, I have to fight off AI "suggestions" and offers of help when I simply want to read a document from the web.

So I set Firefox to use the built-in reader. After 1-2 seconds, it switched to Adobe, and brings up all the annoying AI features. How can I keep Firefox from switching to Adobe?

As a test, I renamed Acrobat.exe to AcrobatX.exe. Firefox behavior did not change. I also killed all Acrobat-related tasks in Task Manager. My document still displayed in Acrobat after 1-2 seconds, but none of the Acrobat-related tasks reappeared in the Task Manager.

I am using Firefox 145.0.2 64 bit in Windows 11 with all updates current.

Many thanks for advice.

I hover over bookmark folder, they expand, and the links the folder contains work. (Or) now 80 percent of the time, I hover over the bookmark folder, they don't expand, so I click on the folder to expand it, and 90 percent of the time, the links in the folder do nothing when clicked on. They won't even get highlighted, (selected) I restart firefox, and all works again, for about 10 seconds, and problem occurs again. It goes without saying it gets real frustrating restarting firefox over and over and over again to use another bookmark. I've never experienced this before. This only happens for me on firefox for Linux Mint 22.1. Firefox on windows 11 does not exhibit this problem. Please help, thanks. Cheers...

I have an website which I prior to this error message have visited many times on Firefox and had no problems. Recently though around two days ago I noticed that I couldn't get in and was met with the following message "Warning: Potential Security Risk Ahead". I can't bypass it apparently and I really need to be able to access this site as it's a University site.

I can access the site on other browsers such as Chrome and Edge but I use Firefox as my default browser and I'd like to keep it that way. I'd appreciate any help I can get.

I run the current version of Firefox on a Dell Inspiron 15 3530 laptop under Windows 11 Pro, I've found two webpages that I can't scroll--there's no scrollbar on the page, and the arrow keys don't work. On other pages, there's no problem. but I simply can't scroll thes pages. What's going on here?

I have 3 devices connected to Mozilla account, 2 smartphones and 1 PC and NONE of them are syncing properly, bookmarks sync perfectly and everything else fails miserably. Some part of history does sync but nowhere near the full history. Syncing of open tabs is *completely* broken.

I've purposefully used the environment variable to disable the security sandbox.

How can I acknowledge and hide the persistent warning? Is there any about:config value for it?

Thank you!

I can not access my Outlook/Hotmail account in FireFox. I get a plank page. I have never had this problem before. I have no problem loading it in other browsers. Did something change? How do I correct this problem?
