Diễn đàn hỗ trợ Firefox

For months I've been trying to clear my saved form data as I put in the wrong email address, and when using saved form data sometimes don't notice it's wrong, so replies disappear into the ether.

Under Settings/Privacy & Security/Clear browsing data I have cleared Everything with all check boxes checked, and multiple times just tried the Saved form info checkbox. The wrong email refuses to die along with the related form data.

It is infuriating. Maybe you can correct it manually, or actually wipe it for me? The INCORRECT email is 'bongoots@yahoo.co.uk'. The CORRECT email is 'bongboots@yahoo.co.uk'.

Many thanks, Bruce Clarke

Hello. i noticed that my shortcuts are missing. i went to settings to check if it's enabled (check mark) and it is in fact enabled. tried to reset my computer and the shortcuts are still not there. on the main firefox page there is actually no shortcut icons on there...at all. all of the options in settings work with the exception (of course) the shortcuts. i would like to know why this is happening...thx

I am trying to open a site, but keep getting this message: "Before you continue to the website...

I read online that Firefox is planning on implementing AI features. Given the track record of AI in other browsers leaking private information, bogging down connectivity, and generally being a nuisance towards users, I was wondering if there will be opt out features in future updates? Or know of forum threads that will update with tutorials on how to turn off AI features?

If not, does anyone on this forum have recommendations for no-ai browsers?

Bookmarks in Firefox disappeared and cannot import my Bookmarks backup. I have tried to restore an older Bookmark file through /manage bookmarks/ import and backup/restore to no avail. thank you

"Magically" started working again for unknown reasons.

Up until this morning I could enter calculations in the search bar or the address bar and get an answer without hitting "Enter". Why has this stopped working?

FF 146.0.1 LM 21.3, Bitwarden, Ublock Origin and Dark Reader extensions active.

Edit: browser.urlbar.suggest.calculator is set to TRUE.

REPEATING IMAGES involving . Macbook Air M4 Tahoe 26.2

When sliding from the primary Mac screen to another on the same computer the Firefox image (and ONLY that image) is duplicated on each additional screen image loaded making the use of multiple screens virtually useless.

Hi Mozilla Community,

I am running Firefox on Windows 11 and I'm encountering a strange issue regarding the UI updates.

The Issue: My Firefox browser updates automatically to the latest version. However, my Default Profile is visually stuck on the old UI design. It does not reflect the recent interface changes associated with the update.

The Troubleshooting Context:

• I have verified that the browser itself is technically updated (via Help > About Firefox).
• The strange part: I have other Firefox profiles on this same machine. When I launch those profiles, they correctly display the new, updated UI.
• This issue is isolated strictly to my main/default profile.

Has anyone experienced this mismatch where the version number is correct, but the UI fails to refresh on a specific profile? Is there a specific fix for this?

Thanks in advance for the help.

When I play YouTube videos in Firefox, the video stutters and drops frames, even when set to 480p. The audio continues to play normally. This issue does not happen in Chrome on the same laptop.

The problem started about a week ago. I’m using Firefox on Windows 11. Restarting Firefox did not resolve the issue. I’ve attached screenshots for reference.

We have a question about bookmarks sync, with specific characteristics, please.

We purchased another computer, a laptop, and wish to benefit from the bookmarks sync between them. However, we're affraid of a backward syncing situation. How can we make sure we prevent that?

For example, say we worked on the desktop for a week, and then need to use the laptop. What should we do when we turn the laptop on and open ff browser, if we wish to sync from the desktop to the laptop? Do we press the Sync button on the laptop? - or will that force a backward synching from the laptop to the desktop? If that's the case, than how do we sync reliabely? And let's say the day after, from the now-updated-laptop to the desktop? Is the safest way to do it by turning the sync option off, and copying the bookmarkbackup folder from one updated computer to the other?

Also, this may complicate things a bit - We use the browser bookmarks in a non traditional way. It's kind of an archive for us. The .jsonlz4 file size in bookmarkbackups folder is 37MB. We remember reading somewhere before, the server backups stores files up to 10MB. So, question is, does the large size or the bookmarks file will affect the synching process between computers?

Thank you very much! :)

I just installed Mozilla VPN but when it's active my internet connection stops working. Pretty sure whatever protocol it's using is the problem with the WIFI signal, but I can't find how to change the protocol like every other VPN service allows. How do I change the VPN protocol? There is strangely no article already on this site for this common problem.

All of a sudden I can no longer add bookmarks to my Firefox desktop. At this point I can not even access the "Bookmark current tab." Are there settings that control the Bookmarks section. Thank you

when I right-click a highlighted word in Firefox browser - to 'Search Google for...', it takes me to Yahoo.com instead, although Google is defined as 'Default Search Engine'. Why? How to fix it to Google search?

I receive this Error msg trying to access Settings option in the AJC epaper section https://editions.ajc.com/shortcode/AJC412/edition/f117d96a-c78b-4df3-4b6a-0e587f6cfd22 on a Firefox Browser:

Application error: a client-side exception has occurred (see the browser console for more information).

I have a pretty through bookmark system. I use folders a lot, and the little window that pops up presents too much confusion if there are a lot of folder already open from previous bookmarking. Is there a method to have bookmark manager open by default upon selecting the bookmark star and allow me to bookmark the current page? Is there a default setting that will open the small bookmark window with all folders closed? If not how do I go about making a suggestion to Mozilla to include this in their next upgrade.

Thanks, Steve
