Diễn đàn hỗ trợ Firefox

I uninstalled Firefox on my computer and reinstalled it, but when I logged in, the account couldn’t sync, it was as if the sync couldn’t retrieve any data from the server. Nothing happened at all.

On my Android phone, the data is still there, but when I tap “Synchronize now,” nothing happens either. I’ve tried signing out and signing back in multiple times, but still nothing works.

I also tried switching to a different computer and a different internet connection, but it still didn’t work.

What should I do now?

I wanted to open firefox and a new window for new firefox open but did not suggest me to sync my old bookmarks. instead it only asked me if i wanted to sync with chrome browser only. why was i not allowed to save old bookmarks before new firefox updated.

PLEASE READ THOROUGHLY - Thru Firefox, I use Tineye to find related photos - I use it all the time, it's been great - I always use a VPN and have never had problems until now (as of yesterday). Now it won't search, a verify you're human window comes up, and I have to keep clicking squares, which I do - but then it says to allow cookies and start over. Well I don't want to allow cookies (Firefox-Mozilla kinda encourages using their tools to block cookies, which I much prefer), and I CANT FIND WHERE TO ALLOW (not yelling its just that I said this before and it wasn't noticed) cookies even if I did (I went to Firefox preferences all I could find was under privacy & security cross-site cookies but that did nothing) and I don't want to disable my VPN. Maybe I should mention that I just added or started a Mozilla account, as I have had immense trouble with my aol emails, and am trying to move everything over to a gmail account. My sign in to Firefox was the aol email, and I had to try (I thought I did it) add another account, which I think I did successfully. So it was right after that, that all this started. Help please! Thank you! I did get the following reply, saying to allow cookies (BUT I DON"T KNOW HOW OR WHERE TO DO IT) and something about a new browser profile and to stay out of my sync account, and I APOLOGIZE, but I have no clue what all that means. What is a broweser profile, what is a sync account and how do I stay out of it? I guess well I know i'm not too smart about this kinda stuff, so I apologize but I think I need detailed step by step what to do to fix this. I know thats a lot of typing, sorry.

Is there any addon or feature within addons management icon (from toolbar) to Disable Extensions and Apps in one-click like Chrome has via this addon?

every time I enter some words for a search the system blocks access with an "I'm Not A Robot" process. while I always get past this it is annoying and has only started happening in the last few days.

I have a firefox account that I use for work, which was created with my personal email address - "email"@"personalDomain".co.uk. When I try to log in using it I get a message saying that "personalDomain.co.uk" is not a valid email address. How can I log into my account which was created using this email address? The email address is valid and active, and I do have access to it.

I just got a new to me computer and it has Firefox 125.0.3 (64bit) but I was more comfortable with what I had Version 124.0.2 (64 bit). What would be the downside of changing to what I had? I just use it for home use and browsing. How would I go about making that change. I'm not to knowledgeable about computer language and stuff. Thanks, Larry

I keep receiving a popup seeming to be from McAfee security regarding a virus on my computer. It isn't from that security firm. The ad locks my system till I shut off and restart my computer. This is very annoying and occurs on all installed browsers. Is there anything I can do about this annoying thing?

There's one specific field I fill in very often and for some reason Firefox is really keen on suggesting me two searches that I looked up more than a couple months ago, on a totally different site. I can't even remove these suggestions or add new ones. When I used Vivaldi, it'd learn what I insert (even if it'd end up suggesting tens and tens of options), while Firefox doesn't learn at all.

For sake of an example, let's say that the word I use every day in this field is XYZ. Not even once was it suggested to me, I've only ever gotten the two in the screenshot below instead. And I can't remove them using the Delete key as some other article suggested.

Speaking of which, I just noticed the same thing happen to the subject line in this form 🙃

Over the last five hours, I have gotten 27 emails from Firefox Monitor for this data breach, for the same email address. I have already marked the breach as resolved in Monitor but I keep getting emails. Is there anything I can do about it?

I made a small CSS customization to my tabs in FF 115 ESR on Windows 7, so they would be flat on the bottom and rounded on the top, looking a bit more like tabs instead of buttons.

Looked ok in FF 115 ESR.

However, in FF 125, half the tabs are now cut off, including their text (see attached images).

Also the tabs background is darker in FF 115 ESR, providing more contrast between the tabs and the tab bar. In FF 125, it's almost all white and I can hardly distinguish between the tabs and the tab bar.

Why is there such a big difference in appearance between FF 115 ESR on Windows 7, and FF 125 on Windows 10?

Here is the code I used...

/* ------------------ RESIZE TAB BAR ----------------------------- */ \#TabsToolbar { height: 27px !important; margin-top: -1px !important; margin-bottom: 0px !important; } \#tabbrowser-tabs { height:25px!important; min-height:25px!important; }

.tab-background-start[selected=true]::after, .tab-background-start[selected=true]::before, .tab-background-start, .tab-background-end, .tab-background-end[selected=true]::after, .tab-background-end[selected=true]::before {

 min-height:25px!important;

.tabbrowser-tab {
 max-height: 25px !important;
 border-color: #8f939e;

 max-height: 25px !important;
 border-color: #8f939e;

} /* ------------------ TAB HEIGHT END ----------------------------- */

I inserted backslashes at the beginning of the first 2 lines of code above to preserve the hashtag sign (otherwise it displays an index number before those lines), please ignore the backslashes.

I would like my customizations in Firefox 125 to look like the ones I made in 115 ESR.

Is it possible?

Thanks!

Hello,

I have three devices: a desktop and a laptop with Windows 10, and another laptop with Ubuntu (LINUX).

I read that I can purchase a VPN installation. Do I need to buy three separate VPN installations or one with a single login and password?

Thanks, Pavel

Hello,

First time posting here, so I'm hoping that someone can help me out.

I'm encountering a very odd issue on my Macbook Pro running MacOS Sonoma 14.4. I am unable to access two sites – allrecipes.com, and seriouseats.com on my home WiFi network on the Macbook.

These sites work on other browsers (tested on Safari and Chrome), and they also work on my iPhone.

Oddly, when I went to work and tried to access these sites via WiFi using Firefox, I was able to.

I am unsure what the problem is – the ability to access these sites on Safari, Chrome, and my iPhone at home suggests that it's not a network issue. I haven't encountered this issue with any other sites.

I am attaching three screenshots 1) The error message that I'm seeing for allrecipes when I attempt to access the site 2) The security tab which shows that the connection is unencrypted for allrecipes (home network) 3) The security tab showing that the connection is encrypted for alrecipes (work network)

Thanks

It doesn't matter if I add www.youtube.com site to hosts file in Linux and delete cache, Firefox just doesn't block it, bypassing my meassures to prevent me to get hooked up here. It was blocking everything as expected some weeks ago. I also tried redirecting to different IP's and it didn't work.

After some checks, I noticed:

• It happens only with www.youtube.com, it doesn't happen with youtube.com (without www)
• Other common pages like other Google pages, Facebook, TikTok or Instagram, get succesfuly blocked by hosts file as expected
• I have tested creating new profiles with about:profiles, but the issue continues
• The issue started after Firefox Developer Edition version 125.0b1 as you may notice in the images attached.
• I also tested with the latest nigthly version and the issue continues.
• DNS over HTTP (DOH) doesn't seems to be the problem since it seems that my network doesn't met the requirements to enable it, and if I manually make sure it's disabled, the issue still continues.
• Chromium browser blocks www.youtube.com as expected, so that indicates my PC might be correctly configured
