Firefox Support Forum

Hello guys. I'm using RPi 4 8gb w/ Raspberry Pi OS latest version and while I'm taking my course the videos are not playing(I tried in Firefox ESR and Chromium). I already ask for support to Udemy Support and they told me that the problem was not on their part. I tried researching the problem but i can't seem to find the right solution so I came here hoping someone would help me fix the issue.

I hope I make my statement clear to you because English is not my native language. Thank you.

Here is the image of the error.

I don't now what happened but my tab bar has a different look to it now. Possible a Firefox update changed the look of my tab bar, but nonetheless, it is now harder to see the tab bar. It seems to have a more transparency look to it making it harder to see the tabs. How do I change the tab bar look to what it used to look like, which was easier to see? Can someone help? Thank you.

Recap: I was having what I believe were some kind of syncing issues, where none of my passwords would autofill, and I couldn't save new login information, and was getting logged out of websites that I would normally be perma-logged in to. At the same time, I have also been having connectivity issues where FF loses connection to my internet for around 5 minutes. Sometimes it would fix itself and other times I'd have to restart FF. Meanwhile, Chrome would run fine in the background so I know it's not my actual wifi but it's specific to FF.

I have tried the FF "refresh" and when that didn't fix it, I tried a full uninstall/reinstall which fixed my syncing/password autofill issues but not my connectivity issues.

Any other ideas? I'm super bummed about this because I've used FF for many years and been so happy with it and have convinced so many friends to jump ship from Chrome over to FF. But I don't have time to keep troubleshooting this and it's looking more and more like I'll have to switch over to Chrome if I want to have a normal workday without frustrations and interruptions.

I have 72.0.2 64 bit browser and it’s worked perfectly for about 3 years with my Word Press account a couple of nights ago I was using it as usual, the next morning I went to open one of my blogs to edit on Word Press and the page begins to open but then it stops leaving a blank white page with the typical ? Mark in the lower right corner for help. I've tried several things to find out what happened but nothing helps. All features on my Word Press account function fine just not Edit! Any Ideas? TY Very Much.

FF auto-updated to 89.0.1, now a site won't work, would like to RESTORE deleted/cleared COOKIES (?!?!) for that site to see if it will help cuz deleted the cookie for it made things worse! Doesn't work under Private FF session either!!

Specifics: I am the Webmaster of (we use WIX to create/manage it) 12cdrc.org and it is working fine using Edge, Chrome, Brave, but no longer works correctly (since 89.0.1, I think happened late last night early this morning on my system) update. Most of the page loads, but the Calendar and display tweets sub-windows will not load! It will be obvious to all where they should be displaying but are not!

So, I tried removing 12cdrc.org cookies. Things got worse! Now the Login won't work either, where I was logged in as my user for the site prior to that.

I tried a Private window/session, and the Login function does work, the Calendar does show, but the tweets sub-section/window still does not display/function.

Background: This is not the first website to malfunction using Firefox... Previous version updates broke the rescuemichigan.com website (none of the pull-down menu functions work, but work fine on/with Brave, Chrome, Edge)! Also mewe.com acts up using FF at times, but a clear of the mewe.com related cookies and relogin at mewe via FF clears up the issues of things not wanting to display correctly or fully on mewe using FF - which is why I thought clearing 12cdrc.org cookies would help in this case (but did not, again, made the malfunctioning worse)!

This makes little sense. I even tried doing D/L of full 89.0.1 install, didn't help.

I'd like to try and RESTORE COOKIES (last thing I want to do is clear all data/cookies for FF) for 12cdrc.org from manual offload of all my userid appdata folder/sub-folders to an external drive (or perhaps appdata backup to Norton cloud backup done a few weeks ago)! But I do not know where to look. Was about to go to my external drive and do complete file search of "12cdrc*.*" to see what would return when I thought I could search Mozilla/FF Help on "Restore Cookies" but only very old question for very old version of FF showed up and it said "IF STILL NEED HELP ASK NEW QUESTION" so here I am doing so!!!

Again, all sites (12CDRC.org, MeWe.com, and RescueMichigan.com) ALL WORK 100% error/issues free using Brave, Chrome, Edge, so this is FIREFOX SPECIFIC and all these issues have started under/after recent FF updates and/or gotten worse, not fixed/better, under updates/upgrades!!!!

Appreciate any Help... 1) like I said, where the Cookies are hidden that I might then recover them from previous save 2) other suggestions?!?!?!

It's awful. I switched from Chrome because it's a CPU hog, but FF is absolutely USELESS. NOTHING works. It crashes if there's more than like 5 tabs open. It WILL. NOT. PLAY. YOUTUBE. I have only one extension-- adblock-- and basically any site with blocked ads becomes useless. Convenient... These problems started literally the first day I used it. I've cleared cache etc, safe mode, and made sure the hardware settings were right. Nothing works. Piece of garbage. Good job screwing up a half decent product. It's crap now. Waste of my time.
