Diễn đàn hỗ trợ Firefox

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 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.

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.

What settings do I need to get Street View to return the street view rather than a black screen in all 4 of my Ubuntu browsers, when it used to work fine but now is trash ?

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.

Tonight I was roaming around my Firefox settings looking at something else, when I noticed this AI piece pre-checked. Why is FIREFOX, who is supposed to be for privacy and security, authorizing an update that automatically choose AI? Not cool Mozilla. Not Cool. Anyone else have this? and yes, I've already fixed it ;-)

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 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.

I have downloaded Firefox ESR and think it has been installed on my masOS version 10.12.1 and am wondering if I can use it on this version after reading your warning about support. Perhaps I have not installed it properly as I have just used what I think was the previous version since it has all the oldsaved sites.

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.

Choices? I need to understand the App before committing my internet presence. Options to revert to Firefox/Windows, disable features I choose. Otherwise it just GQQle. Sync is already intruding on my preferences.

Firefox is preventing me from going to certain websites because it is telling me I am using adblocker but I have none installed.. I am trying to play around with the settings but I still can't do it. Is there an inbuilt adblocker? I need help please...

I really miss the home symbol (a little house), as it allowed me to go back to the original page- blank. I could just start over without having to clear the address bar. It was way better than without it. Any way I can get it back?
