Firefox Community Forum

I have an account with Chewy. When I try to access the link to "My Pet" I receive this message:

400 Bad request Your browser sent an invalid request.

I don't understand why or how to correct it.

Been using Firefox since the 90s and been on Mac since 2000s. This problem has been happening for about a year, throughout three macbooks (my old one, a temp one, and my new one) and multiple Firefox updates. I'm always updated and always clear cookies daily.

The failure to move bookmarks I can overcome by rebooting Firefox with a Forced Quit. If I only have to do this every few weeks, then no biggy reinserting all my passwords for all the different sites I use (and no, I don't want to use password managers, I don't trust them)

Today it happened within hours of Force Quitting Firefox, this is too much!!!

The only reason I didn't report this problem earlier is I simply expected an eventual newer version of Firefox to fix this bug.

Firefox 133.0

Normal behaviour: click-drag bookmark within bookmark menu pull-down to position where I want bookmark Failure behaviour: click-drag fails to move bookmark, until I reboot Firefox, then it works again

Certain items in the browser black out completely. For instance, when I open a google sheet; in the first 3 seconds, I can see the spreadsheet. Then, suddenly, it blacks out. The same is true when I try to open pdfs. I'll add screenshots.

Since the last update, 133 at least I believe that is the last update, I CANNOT LOG INTO Firefox for my PC. I have always used Firefox as my Primary Account therefore, once I have logged into Firefox I then log into my other programs such as Outlook.Live.com. Yes, I know that is a MS program. When I say I cannot log into Firefox.com this is what I mean. I click on the Firefox ICON in my task tray and Firefox appears only because I am NOT logged into Firefox. Then I am asked to Download Firefox for my PC. Of course, I know it is already downloaded and depending on the day I will receive a message saying Firefox is already downloaded or it may download it again. No matter my decision, I rarely have an opportunity to log in, unless I use a round-about way of going through Microsoft. Most of the time the application menu does not appear and when it does appear, and if Firefox allows me to use my credentials to log in, then I wait and wait and wait and the only thing that happens is NOTHING. I'm left staring at a blank screen. Since I've always used Firefox as my PRIMARY, after logging into it I then log in or open other programs I use such as Outlook.Live.com (yes, I know that is a MS program). After years of using Firefox I have never had to look at a blank screen and when I'm lucky enough to see the log in, I attempt to log into Outlook. But, I haven't seen Outlook in weeks. I have to use a round-about way of logging into Microsoft to log into Outlook, sometimes that works and sometimes it doesn't work. It's as though Microsoft and Firefox have found a way to merge their programming. As you may imagine it takes me over an hour to use the programs I need. 'AND, here is the icing on the cake. Mozilla Firefox no longer monitors Trend Micro Security which I have used at least 15 years. At one time, Firefox did monitor TM as an add-on but no longer, and when I checked to see the latest update you were showing, it is obvious you are not keeping up with TM's many updates. I have received some very strange messages from websites I previously log into on a daily basis, such as Grammarly and Pocket and have been redirected to a Microsoft page indicating I owe money, which I DON'T so that was another waste of my time clearing that up. Now, I have gone days without logging into my PC out of sheer frustration. I don't know what else to do and now I'm not protected with a Security Program although I do update and run it everyday. Yes, I am aware of Microsoft's firewall but I'm not sure how well that is working since my PC is now out-of-date. I suppose I could start a Go Fund Me page to earn enough money to buy a new computer...lol I desperately need help. BUT, I CANNOT understand your computer talk, I need things explained to me in everyday language. I hope this makes some sense. Rhonda Caywood

For several weeks now, whenever I try to log in to a google account, Firefox crashes. The crash happens on the screen where you enter your email address, before the page where you enter your password. I start to enter my email, and about 3 letters in to typing my entire browser freezes. The crash also happens in troubleshooting mode, so I know that it isn't a problem with one of my plug-ins. This isn't an urgent issue, I can get by with the gmail accounts that are already logged in, but it is really annoying.

I've used FF for years. The last year, it does not function correctly on about 20% of sites. I suggest focusing on making it compatible, rather than requiring sites that are perfectly coded. I may have to drop FF soon.

Bonjour, Depuis quelques jours lorsque j'accède à ma messagerie Orange, Firefox modifie systématiquement les @ en . ce qui ne me permet pas de réponde aux messages, de les transférer ou autre opération. Merci de bien vouloir examiner quelles sont les raisons de ces problèmes. Bien cordialement. Claude JAMONAC Mobile : [removed phone# from public]

This browser is awful. When I go to websites today nothing shows up and if it does I can't make a purchase because that screen won't show up. I'm being blocked from sites I typically use. The Notifications keep popping up even though I turned them off. My saved screens keep popping up. I should be able to multi task!

Hey all. I am having some connection issues with my secondary comp. Firefox 132.0.2

I recently moved and am getting my home office set back up. Nothing was changed during the move other than shutting down, unhooking everything and setting it back up at the new home. My secondary comp is used for live streaming various TV channels, Youtube, live radio broadcasts etc. Youtube, Google and Gmail loads and works fine. Several of the TV channels load the page but will not stream. Rumble, the two radio stations I listen to and our website host access page all give me the Server Not Found screen. It also fails to update Firefox. Also, my Thunderbird will not download new emails. Now here is the weird part. I can go to all of these sites on my main comp and everything loads and works fine. Any ideas? I have tried changing different settings but nothing makes any difference. I even disabled the firewall.

Thanks.

Firefox prompted me that my local storage space was insufficient. When I opened the data management page, I found that a particular website's local storage was abnormally large, and some websites were inaccessible or unable to log in. After restarting Firefox, the issue did not reoccur.

Hi Firefox community,

I’ve been using BuildMasterHQ to streamline CI/CD pipelines for application development, and it’s been a great tool so far. However, as a Firefox user, I’m curious about how the platform ensures compatibility with some of Firefox’s unique features, like Enhanced Tracking Protection or strict cookie policies.

Has anyone noticed any issues or specific optimizations for Firefox when using BuildMasterHQ? Also, are there any settings in Firefox that might improve the experience further when working with similar web tools?

Looking forward to hearing your thoughts and advice!

Firefox has been put on Flathub, but it only supports X86. Unfortunately, many Linux distributions are slow to update Firefox for ARM. Other ways to install Firefox have poor reliability. Please add Firefox ARM support on Flathub.

On my new Computer I installed Firefox.

In one User Account the Sidebar has the new look (ref. Screenshot) whereas the other gets the old style, where you can either see or hide the bar completely.

Any advice to get the new version for both users - I cannot find the pertinent setting.

I had to uninstalled FireFox because of googletagmanger.com. It was causing me problems with all my websites, favorites, and Proton Mail email.

I tried several times to uninstall and reinstall FireFox, but googletagmanger.com kept still showing until I deleted FireFox and stopped using it.

I only have one place where I can download the iOS FireFox browser app and that is from the Apple Store. If I tried to type it to get it from online, it takes me to the Apple Store. Some day I would like to go back and get the app but the googletagmanger.com would have to be removed.

I accidentally updated my email site password to the wrong one. Previously, I had the correct one saved in Mozilla, but the wrong one were overwritten and I lost access to my email account. Is it possible to recover the password from before it was overwritten with a new one? I have no other way to get to my email, it was created long time ago and I had no backup email connected to it. You are my only hope to recover it- I checked all other options. Please help my case. Thank you for your time dear support grand master.
