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

If you can help me...BLESS YOU!!!

A routine update from Firefox version 99 to version 100 caused Firefox to quit loading web pages, including the Settings page. Firefox appears to load normally but will not display any web page. The only thing that works consistently is Help/About Firefox. System: Lenovo E495 (AMD Ryzen 5 3500U) running Windows 10 Pro 21H2, build 19044.1706 Symptoms:

• Version 100 and higher work correctly in trouble-shooting (safe) mode
• Refresh does not resolve the problem
• Manually removing extensions (NoScript and Cookie AutoDelete) does not resolve the problem
• Uninstalling Firefox and existing profiles (all Mozilla folders in AppData/*), then making a clean install of version 100 does not resolve the problem
• Removing version 100 and reinstalling version 99.0.1 restores normal operation (repeatable with higher versions)
• Updating from version 99.0.1 to version 100.0.2 or version 101.0 does not resolve the problem
• I have not tried removing any Mozilla registry keys

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

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.

The styles look astonishingly wrong, I really think it is a problem on my end, but cant figure out how to fix it, as you can see in the pictures, text is incorrectly sized and/or justified, color gradients are also weird looking, as well as sizing of many elements and tons of other things.

I have tried to completely remove Firefox from my system and reinstalling it, that did not seem to fix it. The reason I think is is a problem of mine is because i was playing with fonts (emojis weren't working on my system,not on Firefox tho, now they are in both)

I don't think the things i did with the fonts did anything to Firefox, since this problem only showed up on Firefox, but since the problem arrived just after a reboot while I was installing and removing the fonts, I think its important to mention.

To sum up I think the problem comes from my local configuration of Firefox, I probably did not delete it all before reinstalling, I am running (Arch btw) a current version of EndevourOS.

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!

Is there a way that I can express my trouble using gmail in Firefox, but have the gmail accounts work fine in Chrome and Edge? In Firefox, my gmail accounts show me as LOGGED OUT, when they are supposed to be logged in, and Firefox will not allow me to log into them again. I have 3 gmail accounts, [edited email from public] @gmail.com is my most active, but none will work in Firefox anymore, but in other browsers, they work fine. All other tabs I open in Firefox, works fine, so it's only my gmail accounts, that has trouble in Firefox. What can I do to correct this?

Thanks

Paul

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!

Hi,

My partner has an issue with Google working within Firefox (FF). The problem started around 27 April 2022.

In short:

• • Both gMail and Google Drive keep saying “Ooops … the system encountered a problem (#2003) - Retrying in x s…” and “Not Connected”.
  • The above message may stop for a period and then gMail within FF fails to render its pages properly. Icons go missing. For example the check boxes to the left of the emails disappear while the remainder of the subject lines remains. Menu icons across the top of an open gMail document disappear (like Download, Report Spam and Delete icons ….). This seems to suggest a cache issue.
  • Search within FF using Google fails also. After entering search terms and pressing ENTER, nothing happens.

Note:

• The stand-alone Google Chrome environment works fine. So gMail, Google Docs, Sheets etc work OK in the stand-alone Google Chrome app.
• Duck Duck Go search works within the FF browser.
• I have noted that if I simply log into MY Google Account under Firefox on her PC the same problem occurs.
• If we log into my PC the problem is not apparent using either of our Google Accounts. So it appears to be an issue on her PC.

I have tried :

• Flushing the cache in FF for all time, including data. Then rebooted.
• We have followed your procedures under “Help” ie Runs a Firefox a tune up; used “Diagnose issues” and “cleared the startup cache”.
• Have run Sophos AND MalwareBytes across the whole laptop. No PUPs or malware detected.

I uninstalled FF using Revo Uninstaller which initially uses the standard FF uninstall exe then it scans the drive for removes all FF files and entries within the Registry; then I re-installed the latest version of FF. Rebooted. No luck here either. I assume there is some remnant file that remains on the hard disk as some settings are retained after a new install.

Hardware: Lenovo ThinkPad , model 20QFS00B00. OS: Windows 10 Pro, vers 10.0.19044 Build 19044, 64 bit Firefox browser: is up-to-date; vers 99.0.1 (64 bit)

I can't find any recent issues related to this specific problem. Please advise what to try next.

Of course I'm happy to provide additional info if required or work through different scenarios to isolate the issue(s).

Thanks in advance for any assistance, Steve Gee

Every time I enter a link to a google service, I see a notice that says "Your should be redirected in a moment..." and then I get redirected to the Stanford University website (https://pass.stanford.edu/signin.html). It is not a specific website redirecting me, but rather some algorithm is detecting a google link and sending me to Stanford University instead . For instance, if I paste in a link to a particular location in Google Maps, I will end up at Stanford instead. I have no idea how to fix this, but it makes me avoid Firefox and use Chrome because Chrome does not redirect. I would rather use Firefox.

On the page: https://support.mozilla.org/en-US/kb/manage-downloads-preferences-using-downloads-menu#w_downloads-panel-automatically-opens it says: "Downloads panel automatically opens" "Every time you start a download, Firefox will automatically bring up the Downloads panel by default, . . . "

It never used to do that ! Having the Downloads panel drop down and just sit there covering a large part of the page every time I save a little picture is an extreme nuisance ! How do I prevent it from happening ? Please help ! Many thanks !

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.

Anyone know how to lessen the time that this pointless thing occupies my screen? It's only 4 seconds but sometimes it's in the way. I'd be okay with eliminating altogether too. Thanks in advance.

When I right click Firefox in my taskbar I have a list of "recent" links show up. I have turned this off in about:config but they still show up. Any suggestions?

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)?

Hi,

In the parameters, I chose to let Firefox ask me every time what to do with PDF files. But, when the window pop up and I click "Open with ... Firefox", the browser download and open with Firefox the PDF instead of only showing it in Firefox. When I set the "Open with firefox" by default in the parameters, Firefox will this time directly open the PDF in the browser instead of downloading it.

Are you aware of this bug ? Is there a solution ?

Thank you very much !

This bug occurs very randomly, but it seems there have few things in common.

- Occurring on domain level, one domain at once. For example, if Youtube.com stuck, any sub address including each video page is not loaded. Other website and whole browser works fine. - Other program on same PC is not affected, too. - Which page is stop loading is completely random. It might be happen only on a popular, feature-rich site like amazon, google, but not sure. - The timing is also random. Maybe after waking PC up from sleep, but not sure. Frequency of occurrence is once every 1~5 days. - The workaround without restarting browser is 1.)switching to other container tabs(strangely), 2.)opening website on private window. Disabling all the addon manually didn't help.

Since it's randomness, I didn't have any logs about this issue.
