Firefox Community Forum

I've been having issues with Cross-Origin Request Blocked errors for a while now. I'm on Windows 11. I first noticed this issue when visiting YouTube. I would go to play a video and any video I tried to play would just load forever and never play. Then I noticed I was having the same issue on Facebook. The page would load but then a majority of the images wouldn't. I can use YouTube and Facebook just fine on Chrome. The reason for the error shows as "CORS request did not succeed". Initially I tried uninstalling all of my extensions. Then I completely uninstalled Firefox using Total Uninstall (for good measure). Nothing has worked. I'm not sure what changed that would cause these errors. Could this be a network issue? I've been having issues with certain sites on my Macbook Air as well (Chrome and Safari) but I thought maybe that was because it's pretty old and not supported by apple anymore.

Firefox will not load my default page (gmail inbox) when launched. It takes me instead to the google help page, specifically for cookies and cache clearing. My other installed browsers work fine with launching my google account and all its apps. Image upload below is of the page that pops up. The sign-in button does not work.

How do I remove the stupid sidebar??? I ve always loved Firefox but Ive just reinstall Windows and then Ive installed Firefox. And this ridiculous sidebar showed. Ive marke Show and hide but still keep on displaying, stealing space from my browsing... :(

I am trying to set the default Map application to Google Maps, which is the best. Apple is the worst. I like the Duck Duck, and want to keep it, but this map problem doesn't even allow Google Maps to appear in the search results!

This is an hard problem for me -- Apple sold out a long time ago and offer an inferior app.

Is there any solution?

BTW, I NEVER SUBMIT! I SEND.

I love Firefox, I use it on all my devices. And daily I access facebook.com on this browser, it's been working flawlessly - until yesterday. Yesterday, using Firefox (ver 130.0.1) on my Windows 10 PC, I tried accessing a FB page which I visit sometimes: https://www.facebook.com/OpenOscillator

Rather than reaching that page, I got a white screen with this error message: "Sorry, something went wrong." And since then, even visiting the Facebook home page (or any other FB page) has the same error message.

Today I tried the same thing on my Mac (OS 14.3), using Firefox and logging into facebook.com, which worked as usual. But when I went to https://www.facebook.com/OpenOscillator, I got the same error message: "Sorry, something went wrong." And as happened on my PC, now on my Mac I can't access any FB page on Firefox.

And just to mention, I've rebooted both the PC and the Mac, yet this problem persists on both devices.

Trying this same exercise on Edge on my PC does not have this problem. Nor does it happen when doing this on Safari on my Mac.

So, this problem has only been happening on Firefox. I can no longer access facebook.com with Firefox. Do you guys have any ideas how to solve this?

Helpful to know: Do you have the same outcome if you visit this FB page: https://www.facebook.com/OpenOscillator

Thanks for your assistance! Steven

logged into mozilla and it ended up in a loop where it kept asking me to turn on caret browsing. every time I hit no it popped right back up immediately. I hit to stop showing the box and clicked no, but now every time I hit the shift key it opens some developer tool box in the bottom of the screen. hitting f7 again does nothing. i can't get the box to come back. i can't make it stop. everything I am seeing online is not helping or references tools or options that i can't locate in firefox. please help.

How do I remove the annoying sidebar on the side in Firefox? I have read and tried all the advice and none work. How do get rid of it permanently? I have read the help from Tech Support etc none work! I do not want it. Thank you.

hello support i have a issues with Firefox browser five or six months ago, which are 1 - the browser keeps resetting the tabs every restart ( i won't find my previous tabs from the last time ) 2- the browser keeps login me out from all my profiles and pages from different web-sites such as Facebook google Instagram and all the others logged profiles ...)

every start i have to log in to every single profile of my web sites and pages ...

Hello! After the recent update, any text I insert remains without spaces and all words are written together. I disabled all extensions: no result. The problem did not occur in other browsers.

'Linked In' technical support are telling me that I am unable to see certain pages on their system most likely because my Firefox Browser (which is fully up to date) is using DNS. They said to remove DNS. Is this wise advice and if so how do I do that and what difference will it make to my day to day use of firefox?

bsky.app cookie continues to be loaded on computer even after I continually delete it, privacy set to strict and blocked under "managed exceptions, why is it being reloaded when I don't access the site. None of the sites I access are linked to it, only visited once and if this alternative to x continues to set cookies, how can I permanently block it, thought the exceptions list was supposed to keep blocking it. So far it's come back three times, I'll screenshot it next time and attach.
