Firefox Community Forum

Thank you for the upgrades to Firefox which I apply. After doing so I seem to lose access to FaceBook and other applications and then have to go through the whole processs of verifying motor bikes, buses etc from pictures before I can access again. It also happens with other applications. This happens EVERY time after I do an upgrade - is there a setting that will not force this change every time please?

Every time I try to use Google as a search engine in Firefox, this message appears. "About this page Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?:

I believe this occurred earlier in the year but was marked as solved. Immediately after Firefox automatically update to 151.0 64 bit today (in Western Australia), I am plagued with it as well.

I have tried disabling extensions and am not (I believe) running in incognito mode.

Any suggestions please?

Mozilla VPN repeatedly gives "authentication error" when I try to log in, I have tried reset but no difference. I am working on Linux Mint with Firefox. Any tips?

Whenever I try to watch videos on websites such as onlyfans youtube, etc., the videos will not play since I installed firefox. I have to shut my computer down and start it all up for them to play. I googled how to fix this and I need to go to settings and scroll to performance and uncheck use recommended performance settings and uncheck use hardware acceleration when available but I can't find this to uncheck these items. Can anybody help me? TIA

I have many computers that I put Firefox on, and had no problem getting my bookmarks on them as long as I sign in to my account. However, I just had my desktop redone (that previously had Firefox) and now, after I have downloaded Firefox, I cant get my bookmarks when I attempt to do the syncing. Please help

здравствуйте, опять проблема после обновления, сейчас 21:41 20.05.2026 по мск. буквально 2 часа назад все было хорошо но возникла эта проблема(поменялись цвета, те что светлее раньше были не такими, на фото в чате выше это видно). На втором скрине поменялось положение выскакивающей поисковой строки, она ушла выше на 20-30 пикселей

OK so, I just updated Firefox to 115.34 Oesr (64-bit) on my Windows 7 Desktop. Before this update, it's been my practice to clear my cookies manually from unknown websites about 3 times a day, only keeping the "exception" cookies. But, since the update, there have been SOOO many cookies...something like 75 to 100 and EACH time I manually clear the cookies...even just minutes after I clear it and refresh the "Settings" page they appear again. And, the worst of it is that Google won't let me sign into Google websites like Play Store and Google.com search saying that "there has been unusual traffic..." and makes me solve capchas all day long. Other sites too say Unusual traffic like CVS and won't let me sign in either. And now, I'm not using a VPN.

I googled the matter and it was said to be was a known issue with the 115 update and the A.I. said to get rid of the ad blocker as a possible fix but, it didn't work. Have Firefox clear cache and cookies but that didn't work, changing "Tracking Protection" to "Standard". Nothing works. Is there an update fixing this issue? By the way, I have had Firefox set to clear cache and cookies upon closing. But the cookies pile up so quickly again. Thanks for your help

Сегодня обновил Mozilla FireFox до версии 146.0 (64-разрядный). После обновления в панели "закладки" (cntrl+B) появился ненужный мне цвет выделения только что открытой мною вкладки (смотри скриншот). Как поменять данный цвет на менее контрастный ? У меня включена "темная тема", цвет выделения - ядовито-голубой. Хочу изменить его на другой более мягкий цвет. Как это я могу сделать?

Today I updated Mozilla Firefox to version 146.0 (64-bit). After the update, the highlight color of the tab I just opened appeared in the bookmarks bar (Cntrl+B) in an unwanted way (see screenshot). How can I change this color to a less contrasting one? I have the "dark theme" enabled, and the highlight color is a bright blue. I want to change it to a softer color. How can I do this?

I am getting a message that secure connection failed, it is happening for Amazon.com and maybe netflix as I can't log on or access the sites

For the past week, I've been trying to set Firefox as my default browser on Windows 11 Pro (I've been using Firefox for years), but after restarting, the Edge browser reappears, even for PDFs (we use Adobe Acrobat) and Paint for TIFF and JPEG files! It's outrageous that Microsoft is forcing users to use Edge. This never happened to me with Windows 7 or Windows 10. I'm completely dissatisfied with Microsoft's policy of forcing users to use Edge! I've tried configuring regedit, gpedit, taskchd, etc., in a thousand different ways, and after restarting, the intrusive Edge returns! Is there any way to prevent this? Mozilla should fight this! It's unacceptable that we have to be tied to Microsoft's monopolistic whims!. Do you have any solution? Thank you very much!! Leonardo
