It used to be that downloading something like a pdf and then clicking on it through the downloads dropdown would immediately open the pdf in the default system pdf viewer. Now I get a pop-up telling me the Portal "Open with" is ready which then presents me with a set of options for where to open the file. I have looked around for anyone else with this problem but haven't found anyone.

Additional info: If I use the show enclosing folder feature it actually shows me a temp folder (image attached)

I am not able to login icloud.com and pass 2 step authentication process. After filling up login and password, message "Failed to verify your identity. Try again." appears. Althrough in mobile phone message with code appears. Firefox 82 unable to change from icloud login page to code input page for authentication.

When saving files, do WHEN TO ASK to open the PREVIOUS SAVE LOCATION. And not every time you open it in a chain, you can naturally change the chain by choosing. + При сохранении файлов сделайте КОГДА СПРАШИВАТЬ, что бы открывалась ПРЕДЫДУЩЕЕ МЕСТО СОХРАНЕНИЯ. А не каждый раз открывать по цепочке, изменить цепочку естественно выбором можно.

Can I turn off the "control media playback via hardware media keys on a keyboard or headset or virtual media control interface" function? (Firefox 81.0, Windows 10)

Hi,

I'm getting a MOZILLA_PKIX_ERROR_REQUIRED_TLS_FEATURE_MISSING error on my website cubox.dev Using Firefox Developer Edition.

Nginx is configured to ocsp response, and disabling this flag in the advanced settings in Firefox fixes this issue, but I can't ask everyone to do that. SSLLabs are indicating that ocsp stapling is working fine: https://www.ssllabs.com/ssltest/analyze.html?d=imonia.fr&s=89.163.242.17&hideResults=on

Could someone tell me why this is an issue? Is there a problem with the way my server is stapling my responses? You can test against my server: cubox.dev

Thanks

I currently have Firefox in Bengali. I can't do it in English. '''''''How do I do this in English?'''''''

Please,help me.

Hello all,

I have been experiencing a critical issue with FF for more than a year now and even though I reported it via the FF crash reporter numerous times it never got fixed so I figured I would report it here.

The issue could be summarized as follow: browsing the website mixcloud.com triggers a memory leak from FF that eventually causes my whole computer to shut down if FF cannot be "force[d] to quit" in time.

Here is a more detailed description I sent to Mixcloud support last year:

"Often times when I open a new page/tab on the website the loading freezes and after a few seconds a yellow warning notification pops up on the upper part of the screen asking: "a web page is slowing down your browser. What would like to do?” with the two following options available: "Stop it" or "Wait". If I click "stop it" the loading will indeed stop and I just have to refresh the page again to continue browsing normally. The troubles begin if I click "wait" or do nothing: the overall memory usage of Firefox will then increase seemingly exponentially and after only a few minutes the whole system will become unresponsive and I will have to hard reboot my computer or it will reboot by itself. This is extremely annoying as you can imagine as every time that happens I lose all unsaved data in the process! Strangely enough this issue sometimes even occur without any notification displayed or freeze happening in the first place: I would be browsing a few Mixcloud pages then switching to another website and after a couple of minutes I would notice that the memory usage is increasing although no Mixcloud page is open any longer... In both cases the only solution I found is to quit/force to quit Firefox as soon as possible to prevent it (and the system) to become unresponsive. Closing the application always resolves the issue and I can see the memory usage of the overall system subsequently dropping sometimes from up to 95% to 40% in the Activity Monitor app. Again I would like to stress that I have been experiencing this issue ONLY on Mixcloud and that I have no other memory related issue on my computer nor with Firefox in general."

Mixcloud support reply at the time: "this is linked to some issues we've been experiencing but our team are busy working on a fix for". 10 months later nothing changed...

The same issue happened again this very morning: I opened a Mixcloud link from google results and even though I immediately closed it, 5 minutes later the RAM usage was at 93% and I struggled during 10 minutes to "force to quit" FF as the whole computer was becoming increasingly unresponsive. I can provide a crash report from this morning but would prefer not to display it publicly.

Please investigate this leak. It is becoming more and more frustrating to deal with as the time goes by.

Hi, I am using Firefox Developer Edition and I am always using DevTools. While I was working, box model disappeared. Can anyone help me?

When clicking on a PDF link, Firefox asks what to do. I opt to view the file in the PDF viewer, and do not select to Save it.

Invariably, Firefox saves the PDF to my Downloads folder before opening it.

This wasn't the case before. This clutters my Download folder as I open a lot of PDFs.

Hi all,

Currently on the latest beta on macOS Big Sur v11 beta (20A5364e).

Crashing of tabs has at least been resolved since previous versions but I am having an endless usability issue. I can have 2-5+ tabs open and clicking on the tab itself appears dead/unresponsive. Clicking a few more times (in different areas of the tab) or selecting another tab then switching back results in the tab being selected/usable/active again.

I am unable to find any common way to replicate this or reason for it - the sites in the tabs are always very much different. It's not the web site that becomes unresponsive as even when opening multiple 'new' tabs, the same issue can occur without even loading a site.

Detailed version info included.

My question is a blend of these two previous questions:

https://support.mozilla.org/en-US/questions/1303566 https://support.mozilla.org/en-US/questions/1277388

I have a bunch of open tabs which used to simply contain pdf documents, opened in the Firefor pdf viewer, with the file URL in the address bar rather than a local temp dir address. This behaviour however changed with a recent update (I'm on 82.0b5), and now when I reload those old tabs, I get prompted for a download, and a new tab is opened following the download with a local temp dir replacing the URL. As all these files previously opened just fine in the FF preview with the URL present, this is unlikely to be related to whether the server sends files as "application/pdf" or otherwise, as the same files have changed behaviour, and it is unlikely that a bunch of servers changed the way they send files at the same time.

Further, the answer to the second question above proposed to select "Preview in Firefox" to get around this, however this option doesn't seem to exist anymore.

Is this a known behaviour change in FF82? If so, is there a way to get the old behaviour back?

After installing the 81.0 update, any flash page I go to is zoomed to the maximum and not able to unzoom. See if this page does that for you: https://radar.weather.gov/radar.php?rid=FWS&product=N0R&overlay=11101111&loop=yes

Every day I get a Firefox popup that says, "Firefox cannot download the latest version. Download the latest version and we will help you install it". Sometimes the popup appears immediately after I open my browesr, and sometimes it appears after I've been using the browser for several hours.

I've been doing the daily download and install, but I want to know what's causing this. I'm using a Late 2015 21.5" iMac running macOS Catalina Version 10.15.7. Firefox is Version 82.0b4, set as default browser with automatic updates turned on. I've been running Beta versions of Firefox for >2 years and have not had problems with updates before this. Thanks for any suggestions and solutions!

I finally figured out why Firefox kept warning me about opening too many tabs at once: this command is the first option on the pop up menu when I click and hold a moment too long on a folder that is part of my bookmarks toolbar (some of these have dozens of bookmarks)

'Open all in tabs'

this is on my Windows 10 PC using Firefox beta.

Is this a command I can hide/delete/inactivate? I'm quite certain I've never wanted to do this and probably will never want to do it, and now on a machine where I use a mouse with right click it is disturbingly easy to click this accidentally. I want to disable the command entirely.

I did check about:config and saw nothing obviously relevant.

The scroll bar on the right of my screen disappears when I sign in to "The Guardian". This started within the last week. It works OK when I sign in to my other on line subscriptions (NY Times and Washington Post) and all other places I access. It works OK when I do a "Safe Mode" load of Firefox. I have explored the few Add-ons and Custom Settings but have not been able to determine the cause. I am having this problem on any of 4 different computers currently running Firefox 81.0 and Windows 10. Microsoft Edge is working OK if I use it.

Any help would be appreciated.

Jim

Not sure if this was already reported, since search on this site isn't great and I have to look through multiple pages.

Sometimes some elements won't want to unselect, and stay highlighted until I close inspect element.

I have an older addon that was disabled. it's no longer supported and won't be updated. I'd like to reenable it anyway. I'm well aware of the general "risks" involved and prefer to have use to my tools.

"Download has been disabled due to security or stability issues." The best I can see is that the inclusion of optional search bar changes is the culprit. I'd be more aware however the admin on the report has hidden the comments and the bug-report is a bit lacking.

I would prefer not to turn off all add-on verification unless I absolutely must. But that's the point I've now reached. I'm using FireFox 82.0b3 on MacOS 11 Thanks.
