Firefox Support Forum

I am sending tabs from Firefox mobile to Firefox desktop (Arch Linux) (on a regular base for years). All worked fine. After a new install two weeks ago the Firefox desktop receives the tabs and opens them as supposed. But after a day or three when I open Firefox desktop it opens all previous tabs again together with the newly sent tabs. I deleted the Firefox profile and installed from Firefox sync but the problem occurs. I deleted all devices in sync and added my 2 devices (desktop and mobile) again but it didn't work. Does anybody have a similar problem (and a solution)?

I don't know if this is a problem with my installation, but websites without specific favicons (e.g.: https://forum.librivox.org/index.php?sid=fd7dca1ba59c207dd25121695677d565) don't have a placeholder icon in the tab. Is this intended behavior? There's the globe icon for bookmarks without favicons, couldn't that be used if a website doesn't have one? I think that would contribute to some visual consistency :)

I have looked across various support forums for information on this, I only see posts regarding favicons and bookmarks, not the tab itself, so apologies if this has been asked and answered already!

Dear Madam or Sir,

since updating to Firefox 99, we are unable to view PDF files in Firefox, because we are unable to select how to handle PDF files in the settings, cf. 1.PNG We don’t have any enterprise policies enabled except for disabling updates, cf. 2.PNG. We tried disabling hardware acceleration, but it did not help, cf. 3.PNG We tried safe mode and an empty user profile, both to no avail.

This problem seems to be irrespective of the user profile because when I roam my user profile to a machine with FF 93 ESR, there is no issue and I can view PDFs in the browser.

Is there any suggestion how to return the built-in PDF viewer?

Thank you very much in advance!

Best regards

Victor

Grammarly.com is not letting me log in because the continue bar keeps loading. It won't let me enter my email and press enter, nor is autofill working. I've contacted them, but the solutions they're telling me to do have had no success. I've already disabled other extensions to see if that was the problem, but it wasn't. I cleared cache and cookies, and I've also removed the autofill option as well. My firefox is up to date.

Hi,

i am having a rather weird and persistent issue. When I try to open a specific website, namely www.westend61.de, this Firefox tab crashes, as seen in the provided screenshot. With a normal website this wouldn't bother me so much, but this page is the main page of the company I work for, and therefore I and potential customers must be able to reach it. That being said, this does not necessarily have to be a Firefox problem, the issue could also be on the server side. But the website works on other computers, other operating systems and other browsers. As far as I know, the website works fine, this computer using this browser being the only exception. I worked my way through the Firefox support page:

- checked for newer firefox version - checked for newer compatible MacOS version - checked for newer graphics driver - disabled all firewall, anti virus software - started firefox in Safe Mode - reinstalled firefox & deleted all profile data - disabled hardware acceleration - set webgl.disabled to true - again safe mode

The tab crashes every time. This computer is an old End 2015 iMac running Monterey and the newest Firefox. - More information can be found in the troubleshooting information and the crash report: https://crash-stats.mozilla.org/report/index/bb11e42d-9fc9-4061-b89c-4c6400220503

Thank you very much.

When I restart my computer, I am logged out of all websites although I did not select settings such as "Delete cookies and site data when Firefox is closed". This only happens with reboots and not on Suspend.

I saw two similar posts but the options look like they changed name since then: https://support.mozilla.org/en-US/questions/1319622 https://support.mozilla.org/en-US/questions/1289909

I tried to apply the solutions linked there, to no avail.

This behaviour only happens on my Garuda Linux and not on Pop-os. Thus I am not sure here is the right place to ask this question.

Another strange bug which may be related is the following: if I zoom in a page (say set it at 120 percents) then go to another tab and then come back to the page I zoomed in, the zoom is reset to 100 percents.

Any help would be greatly appreciated!

Hi there,

After a Firefox Refresh, one site I used to access everyday does not accept my user Id/password anymore. The site did not return any warning message like wrong password. It just doesn't go trough when I hit 'enter'.

The same user/pw is still working well in Chrome. I asked for help on the site I could not access, but they have no issues like mine, and his system is regularly on.

I have already cleared all my history, cookies, everything. I have installed Firefox again. Nothing.

Any idea? Thanks

Hello,

The pop-up blocker exceptions are not working for some sites which I, of course, use a lot. The sites are listed in the exceptions, but Firefox stubbornly continues to block them. I sincerly consider walking away from Firefox (notwithstanding I love it and being a long term user), because it happens with sites I frequently use on a daily base.

I've looked around but none of the solutions work for me as those articles are rather old.

My version of Firefox: 99.0.1 (64bit) running under Windows 10 Pro

Hoping to find a solution here.

Many of my bookmarks are corrupted. They point to other websites, not the bookmarked one. Has anyone else had this problem? Is there a fix? Thanks for any info/advice. George

On my old (Intel based) MacPro Zoho email works fine. On my new M1 chip MacPro when I first open Zoho, or open an email, the page does not render properly at first (buttons/links don't work etc). After a delay it refreshes and shows properly. The delay depends on how fast my internet is - in the evening it can be a minute or so. Even when the internet is good I still get 2 versions of a page with a pause in between.

I tried on Safari and it works fine - which makes me think this is a Firefox issue.

I have some screen shots but when I click the browse button below I can select a file then it just endlessly shows working. I will have to email these to you separately

Thanks Phil.

I've been using Firefox since 2007, and I've had a love-hate connection with it at times. It is not uncommon for updates to wreak havoc on the system. I have to fix everything, and I don't want to use Firefox anymore. With the updates, it's changed a lot of the pages, even the ones that I use daily. I've tried everything to try to fix these problems. Please tell me how to straighten things up.

I am using a Mac and have no idea what this is or how to turn it off, image attached it comes up down the bottom of the taskbar even when firefox is not running. Thanks

Every time I close Firefox, whether normally or using Allt-F4, there is a short pause (1 - 2 seconds) then around 20 - 30 seconds of intense disk activity which locks everything else on my PC (Win 10 pro 64). If I hard shut down the pc (ie, switch off the power) there is no adverse effect on firefox after restart, so whatever it's doing is apparently unnecessary anyway. How do I cure this, it's irritating me intensely - enough to seriously consider using another browser

YouTube TV won't load in my Mac OR my Windows Firefox.

Error: "Please use the latest version of Firefox to watch YouTube TV on your desktop."

I'm running 99.0.1. Enhanced tracking off. Extensions off.

YouTube support has been no help! Any ideas here?

Thank you.

When I log on to the National Savings website using Firefox ( though not when I log in with Chrome) I get the pop-up requiring me to accept or edit Cookies at every page on this particular website. It even happens when I select LOG OFF. Hence it occurs maybe six or more times whilst I am browsing the website. I complained to NS&I but they report it is not caused by their system. I therefore assume it it something within Firefox which is the problem. Can someone please advise me how to prevent these pop-ups. My operating system is Windows 10.

For about a month how I find that the Firefox download list opens by itself multiple times during the day. Most of the time I'm not even actively using firefox, it's just idling in the background. When it first happened I figured it'd be a quickly patched bug and so didn't ask around about it. But I've had a ff update since then and it still happens. Does anyone know why this is happening? I have not seen reports of this via search.

I'm on ff 9.0.1.

When viewing email on Outlook in Firefox, there now appears a rectangular black box over part of every email. This does not occur when viewing Outlook emails on Chrome or Edge. I thought it might be because of my adblocker (Ublock Origin) so I turned it off, but the black rectangle still covers part of my messages (and I have Ublock on Chrome, too, with no problem viewing Outlook).

The rectangle covers only a portion of the messages. When I scroll the message, the black rectangle remains stationary and the message scrolls behind it, thus revealing the portion previously covered by the black rectangle (a different portion of the message becomes covered).

I tried to take a screenshot to show the black rectangle covering part of the message. Amazingly, even though the black rectangle is there when I take the screenshot, the screenshot itself does not display the black rectangle....instead the message appears in the screenshot without being partially covered by the black rectangle.

On certain websites I notices I have 'unknown errors' when trying to log in.

Usually this is remedied by either using Chrome or clearing cookies and the cache.

Both of there are inconvenient and result in a great deal of wasted time.

The usual response by these websites is "get Mozilla to fix this".

I'm getting sick of this.

I don't want to switch to Chrome but I will have to if this persists.
