I cannot sign into Vanguard Mutual funds after 20 years of doing so. I can sign in using EDGE. I have the latest version of Firefox. I have some Ghostery stuff. I have Windows 11.

Anyone encounter the same problem?

When using DuckDuckGo Search I cannot drag and drop the search URL into my Bookmarks. I can drag and drop a Google Chrome search URL into my Bookmarks as usual. Also, the correct URL is not shown for the search using DuckDuckGo. See attached screenshot.

Please resolve.

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

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!

Sometime ago I must have made a typo when entering my email address into a pop-up window in Firefox. Firefox continues to find and use this wrong address in pre-fills but I can't find anyway to correct it. I've worked through Settings/Privacy & Security with no luck. Can someone help please? (Windows 10 Firefox 145.02)

I can't seem to locate how to activate the microphone in the AI sidebar. I have Gemini selected, and when I hit the microphone to dictate I get the following message.. Unable to access the microphone. Please check settings.

I looked through Firefox settings and my laptop's but I don't see where it is turned off or asking for activation.'

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

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 noticed recently that my 'Add Shortcut' button has disappeared. I've been through other articles and they were of no help. I have 4 rows selected for shortcuts so theres no reason for it to be gone.

I run a drafting site where we share shop drawings for contractors and architects: https://usadraftsman.com

Whenever I open these drawing preview pages in Firefox, the browser gets slow or sometimes becomes unresponsive. The same pages load completely fine in Chrome, so I’m trying to understand what might be causing this only in Firefox.

Most of the previews are large drawings or viewer embeds, so maybe Firefox is struggling with rendering them. I tried clearing cache and turning off extensions, but the issue still comes back.

If anyone has dealt with similar heavy graphics or rendering issues in Firefox, what should I check or adjust? Any suggestions would be appreciated.
