Firefox Support Forum

I always use the current Firefox on two Macintosh browsers running OS 10.14.6.

Recently (in only one of the computers), if I download a file, a pane containing recent downloads opens in the upper left-hand quadrant. This is distinct from the downloads portion of the "Library" area, and gets in the way of my ability to use Firefox efficiently.

I can't seem to find a way to keep this pane from repeatedly opening up as I download things. Can anyone help?

Suddenly, when I search the web with a topic search term, e.g. "thrombin", I get the error message: 'The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.' Can you help me resolve this problem?

Hi, I cant log in to any plusnet pages, this is not just Firefox other browsers do the same. I get a message Secure connection failed. All other websites seem ok. Even private browsing is OK but no PLUSNET. I use Firefox 100 and search with Duck Duck Go. Please help as Plusnet can't. Many thanks I.M.

I enjoy listening to https://ici.radio-canada.ca/ohdio online with Windows 10. Since the latest version of Firefox was installed, the audio no longer plays; nothing happens when I click the hyperlinks on the page. The audio plays in Edge and Chrome. I've turned off Enhanced Tracking protection, and the pop-up blocker is off. Any help much appreciated!

So, for a few months now, the preview panel in Firefox has been popping up with every successful download of a file from online. Its a bit inconvenient because anytime it pops up, it basically tabs me off a page and interrupts my writing or the like. This wasn't an issue last year when after successful downloads, the downloads icon in the toolbar just lights up blue to signify a successful download. The preview panel popping up every time Firefox successfully downloads something (due to reasons, I download files in bulk from multiple sources) is incredibly irritating. The problem goes away when I just remove the download icon/panel from the toolbar entirely. I just wanna know WHY this bizarre phenomenon happens.

When I open a website, the message "Firefox is already running" comes up every time. Task manager says nothing is currently running. I have to click "close Firefox every time I go to a website. Can you help? Thanks Alan Murray

I saw where this was a problem with Netflix, Amazon Video and other sites with Fire Fox and that one person even used professional version and still had the same problem.

What I cannot see is where he got the video codex that allow Netflix to work on Fire Fox version 88, let alone this newest version that Mozilla has created.

Since the latest (5 May 2022) update to Firefox (to Firefox 100.0) my Gmail account does not work properly on my desktop running W11. Gmail frequently disconnects for varying periods, then reconnects, only to disconnect again almost immediately. Gmail will not let me open another account from within the current account. This does not happen on my Android phone where Gmail works properly. Neither does it happen when I run Gmail through Edge on my desktop. Hence I presume it results from an interaction between Firefox100.0 and Gmail. My wife has exactly the same problem using her Microsoft Surface Laptop under W10 since this latest update.

Since an update several days ago I am unable to link to sites or email addresses I receive in emails. Serious time waster. Also in some accounts I have had for years they don't recognize my password any longer when I try to log in via a link from an email.

Below is the crash report:

I was using lightspeed POS and routinely get a dialogue box asking me if i am sure i want to do something. in an effort to save .05 seconds, i selected do not let this website ask me again. this unfortunately broke a site function of doing the thing that requires confirmation and im sure broke countless other functions that rely on that confirmation. how do i undo?

Ive cleared cookies and site data, thinking it was sort of a cookie thing and it would reset, but no avail.

Please fix the abovementioned problems,make a browser bit faster,improve the consistancy of the browser so that it will stop crushing.Please make it stop alternating or change mail pages.

Hello, I use a website, MySubaru.com, that has always loaded on my iMac (10.12). Lately what I get is a blank screen whether from the bookmark or the website in Google. Strangely enough, the site loads fine using Safari and on my MacBook and iPhone. Any suggestions? Thank you, Eric

I'm using Firefox 100 on Win10 and can't save any bookmarks. They do NOT appear under the App Data Profile, which would not be acceptable even if they were. This change has made it impossible for me to continue using Firefox, unless I want to go back to Win7.

I simply need Bookmarks to work the way they did before!

Thank you for your time.

After i just updated Firefox to newest version .. I can not load any website anymore!!!!!! please make it so i can return to the previous version ASAP so everything works again.

Al those other solutions you guys give like clear cache disable en able etc don't work and take hrs of time

When oyu push a other update through some 1's throat atleast make it that it A)works B) option to roll back . TY

Is Firefox will support this feature ? Or at which version will support ?

File System Access API

My picture-in-picture remains in full screen, even if I double click with my mouse. When I click the ESC button it just closes completely. I have restarted both Firefox and my computer, but I keep getting the same problem. Not just in YouTube either, also on other websites.

I use the recent activity page as a homepage with the icons of the websites that I most frequently use. but i can't figure how to adjust/pick the icons (websites) that I want to appear on this page. Something is picking them for me. And when I delete an icon another one pops in place but is generally a website I rarely use. How can I choose the icons (websites) that I want to appear on this page?
