Firefox Support Forum

Every droplist is much too short so it doesn't display all entries, it's on the upper side of the page and not below the droplist as expected. I've removed firefox and my profiles, all mozilla and firefox data, when i reinstall firefox it works for around 30-50 seconds as expected and after that time, when i refresh the page it looks broken again.

System: MacOSX Catalina. Firefox 81

All the other apps in Office 365 work as normal but when I launch Sharepoint in a normal Firefox window I get the following error message:

• Sorry, something went wrong
• An error has occurred on the server.
• Technical Details
• Troubleshoot issues with Microsoft SharePoint Foundation.
• Correlation ID: xxxxxxxxxxxxxxxxxxxxxxxxxxxx
• Date and Time: xxxxxxxxxxxxxxxxx

Firefox is up to date (v81.0) and running on a modern up to date Win 10 Pro laptop, I've cleared all my browser history and rebooted but without success. The same web page works without problem in Edge and Chrome but in Firefox it will only work in a private window.

A few days ago my Firefox browser started crashing before it even opens. I'm not very tech-oriented. Can I just delete Firefox then re-download it? I have an older Mac that is running low on storage, so this may have been a contributing factor. I have deleted some stuff and have some storage but Firefox still crashing. I get only a box that says Firefox crashed and do I want to send a report. So I send the report and get no response. I am using Safari for today - but this is not my choice - Safari doesn't load links like it should. Never had ANY problems with Firefox before and have used it predominately for 20+ years.

Thank you for any instructions you can send me on how to fix my Firefox.

I've had Facebook bookmarked on my Firefox browser for years, and have never had a problem logging onto Facebook by simply clicking on the saved bookmark...no need to enter my Facebook password. Over the last few weeks however, the first time I click on the bookmark to log onto Facebook each morning, I'm prompted to enter my Facebook password to log on, use the code generator, etc. The messaging states that my Firefox browser isn't recognized by Facebook, ever after I save the browser again, each morning, while completing the log in to Facebook. After I have successfully logged on each morning, I can access Facebook for the rest of the day by simply clicking on the saved bookmark. But I have to repeat this process each morning. I used the Microsoft Edge browser to log onto Facebook yesterday, went through the whole log in process, code generator, saved the browser, etc., and this morning was able to log onto Facebook via Microsoft Edge simply by clicking on the saved bookmark....no need to re-enter my Facebook password. Is there a way I can fix this problem in Firefox settings, so my Firefox browser will again be recognized by Facebook when I click on the saved bookmark? Thank you.

Since the latest version of Firefox some of the websites I visit are having the pictures blocked when I click on a link of the website for pictures. This problem seems to be most prevalent on adult web sites but not exclusively them only. Up until the last update it worked fine. As a note my Microsoft Edge browser is not having any problems viewing picture links.

Hi, I recently was testing browsers, and I think I will stay with Firefox, but the only con I find is that when you go to a Youtube video, instead of playing it automatically, you have to click it and it's annoying. Is there any way to make the videos to auto-play? Thanks.

I have a website that wont render correctly. It will not render most of the css on the firefox installation on my main computer. I have tried loading that website on multiple computers with the same version of firefox (signed into the same firefox account) and they all work. The website also works fine on Microsoft edge installed on my main computer.

The weird thing is, if I try to load that exact same website when it is downloaded to my computer, (from my hard drive) it works fine and looks perfect (same browser, exact same code).

I have tried to clear my data, and disable all extensions and plugins and that did not work.

Does anyone have any suggestions of ideas I can try before I reinstall the browser on my computer?

I am running Windows 10, Firefox x64 version 81

Hello all, I've yet to test this in great detail. But, it would appear that Firefox is running super slow. It's using about 3GB of ram out of my 16GB (Seems low imho).

When opening websites like Facebook, videos, the message box etc lags. On YouTube videos can lag, and other sites that have elements that popup etc seem to lag.

I only run an AdBlock, and it's even disabled on the pages that lag. These issues aren't present in Google Chrome or Edge. In fact, Facebook is super responsive in Chrome.

I've tried various things to solve it mentioned on this forum, including entering some urls to access more advanced settings which hasn't worked.

Thanks alot.

Hi, When I try to reach Flickr it does not fully load the site but just the top of the Flickr home page, The blue line under the black Flickr heading keeps going across the screen. This has happened for some months now with different issues of Firefox and different Mac OS releases. Currently I am on Firefox 81 and Mojave. I have had to solve the problem by using Safari but I would prefer to use firefox. Any help greatky appreciated. Many thanks Ben Screen grab attached

Posting 10/3/20 I use the current Firefox for Mac and my OS is Mac Catalina. Until recently, I was able to stay logged in to sites between sessions. Now, even though I set the site to keep me logged in, when I return for a new session, if it has been more than a short time, I have to log in again. Site examples are Amazon, eBay, TD Ameritrade, PayPal, etc. I haven't knowingly changed any security settings. How can this be corrected?

Noticed after a FireFox update I am unable to post picture comments to others posts on Facebook. GIFs and emojis are fine. Tried resetting Firefox and deleting extensions. No change. Restarted computer. No change. Can, however, post pics on other browsers like Chrome. Using updated Mac OS Catalina.

No ideas what else to try.

I opened several links in new tabs and one of them wanted permission to install an add-on, which I refused. But that site opened pop-up and browser windows which, when closed, merely opened more windows, and a Powershell window too. It looked very suspicious, so I closed the browser entirely and didn't touch those windows. I want to report that site as possibly malicious, and see if it raises any alerts. But, in closing the browser I lost the site address. I know I clicked "never allow" for that site to install an add-on. Is it possible to see which address or site I most recently clicked "never allow" for? That is the only site that asked to install an add-on for at least a month. I tried re-opening all recently closed tabs again but couldn't find it. Thanks, Bernie

I can't access Twitter via Firefox, as of earlier tonight (9/26/2020). It is obviously a Firefox issue, since I can use the phone app (Android) and I was able to access using Chrome.

this error is saying: "Oops.

The site at https://twitter.com/home has experienced a network protocol violation that cannot be repaired.

The page you are trying to view cannot be shown because an error in the data transmission was detected.

   Please contact the website owners to inform them of this problem."

any idea what should i do and how can i fix it?

I get error msg when I try to access Twitter. Is it something I did or is Twitter really down (hard to believe).

Hello. I am having the same issue as another user, but they flagged their question as solved so I'm making a new one just in case.

I can't login properly to YouTube, only in Firefox, even after clearing cache and cookies and disabling add-ons/running safe mode. I can login to my Google account, view my playlists and recommended videos (although the main page with recommendations only shows 5 lines of videos and when scrolling further is not loading). I can't make any edits, for example add videos to the "Watch Later" playlist, that require a login. When I click login, Google shows the 405 error "The request method GET is inappropriate for the URL /youtubei/v1/browse/edit_playlist. That’s all we know." or with other URL, depending on the action taken.

What can I do? Thank you.

I get signed out of every account (YouTube, hangouts, g mail etc.) and my settings also get reverted ( appearance and font of Duckduckgo) except the Firefox account, every time i close my browser. I have to sign in again and again everywhere every time i close Firefox. This did not happen before; suddenly started happening today.
