tell me whether i can find a window i closed today having multiple tabs, using "history" and recently closed tabs/windows (both). i especially want to be able to restore the tab for Institute for the Study of War and its companions. i hope you are warm and rested.

to do my regular research, i have lost three or four (or more) windows with multiple tabs, as a result of my reorganizing tabs. i think of each window with one of its tabs, so these would be, "Emma Loop" (which includes all federal court districts tabs and related info); "Kyle Griffin" (which includes various journalist/news tabs); "emptywheel" (which includes various journalist/news tabs); and other such similar windows whose name ID i don't remember.

restore scares me because it will apply to bookmarks.

i recently began migrating from twitter to mastadon, and wanted to add my regular tabs to mastadon. i moved tabs to keep track, but it seems the tab's parent windows disappeared. i cannot be more clear, because i had a total of about 15 windows with multiple tabs EACH. i regularly exited the program to install updates and because of my settings, all the windows/tabs were saved correctly. this is a great feature.

it takes time to create a window with multiple tabs, and i don't have much of a brain, so it's hard for me to learn new stuff. maybe we can work together to clarify what i need. i just want my "lost" windows/tabs to return to the others so i can continue going forward. i blame this guy - the "new twitter owner" - who has even made changes to UKRAINIANS' account performances. thank you.

I'm trying to watch videos in Firefox. Youtube works but Xvideos does not. Firefox pops up a window asking me:

>> "Opening xvideos"."com ###.mp4". >> which is: MP4 Video (16.4MB) >> from https://cdn77-vid.xvideos-cdn"."com >> >> What should Firefox do with this file?

My only choice is: Open with Windows Media Player x86 (default)

suggestions?

I'm running Windows 7 Firefox 76.0.1

Thanks!!!!

Hi. Starting somewhat recently, Firefox has been getting in the way of me downloading certain PDFs which I know to be fine but which it thinks are insecure or a security hazard. I'd like to disable this security "feature" permanently. How can I do this? Thanks!

Win 7 Home Premium Firefox Version 101.0.1

'Privacy & Security'->'Cookies and Site Data', 'Clear Data.'

When 'Clear Now,' Cached Web Content; is clicked, it does not zero out. (It used to clear completely).

The browser webpage has been refreshed, the browser closed and reopened, and the computer restarted but the cache does not reset.

This issue started on the morning (Pacific time) of June 26-Is this a known glitch or am I missing a detail?

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]

After last update where the bookmarks bar was is now just a message as shown below saying to place bookmarks here but won't display prior ones or let me add new ones. Also, the >> on the right side that showed a dropdown of them is gone.

I updated my firefox to the latest version : Version 92.0 Now in Bookmarks Toolbar (Show more bookmarks) i have a problem about double Space between bookmarks. This is really really annoying. How can i fix that double space issue?

I tried browser.proton.contextmenus.enabled > false (disables Proton UI of context menus) Did not work for me.

I use Firefox Developer Edition and recently I noticed a problem when watching videos on any website in full screen mode. As can be seen on the attached image, there is a weird pixelated border around the video.

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

• My mail client is completely unaffected and is behaving normally.
• I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
• Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

Since the last update to Firefox I have not been able to print using the system dialog. Only the new Firefox print screen comes up. How can I return to system printing dialog?

Also the ability to set print quality in the Firefox print screen does not exist. I can do copies, black or color, duplex printing, etc but not set the print quality like draft, text, photo, etc.

I also have many forms I've setup for printing and I can't access these.

Thanks, Pat

so firefox I am logged out, you can tell where it say "save and sync - sign in". but even though I am not signed in, my passwords and addons are still showing up.

how to fix this

thank you!!

Anyone seen an issue where Avast flags the Mozilla prefs.js as Gamaredon malware? First time I've seen this, could be a false positive but will avoid Mozilla 'til sure what is going on?

Hi, I have spent hours this morning trying to diagnose a problem with Firefox Update 115. It is Unstable and I can't Stream Music from Youtube or even Amazon Music. Web pages from sites I use everyday are out of order when displaying text as well. It's a real mess. Now, here's the kicker, I haven't been able to stream my music from both aforementioned websites, but get this, if I use the Incognito Browser, Music streams No Problem. Seems like you guys broke something in the main FF browser. I have spent hours trying to debug this and have concluded that your most recent Update has broken streaming links. I can't rollback the Update and that is even more frustrating. Please Fix This. BTW, your Help Pages really stink. Sorry, but they offer no help when the problem is clearly FF. Kind Regards, Joe White

Since I upgraded to version 94.0.1 I can no longer access games at shockwave.com, such as https://www.shockwave.com/gamelanding/the-daily-snoop-a-hidden-object-game.jsp. All I get is the initial splash screen.

It does work on MS Edge and since I no longer have Adobe Flash installed on my computer that shouldn't be an issue.

I have also submited this question to Shockwave. Do you have any suggestions?

Thanks.

I have noticed for awhile now that when I load my Firefox homepage its keeps taking longer, certainly longer than it used to take. Also, when I load a You-tube video it takes about a minute for things to work properly. The video and audio are erratic and skipping and simply disjointed for about the first minute, but then after that period of time the You-tube video runs OK, both audio and video. Something seems to be causing those problems recently that I didn't have previously. The problem seems to just keep getting worse also. I would appreciate any input and suggestions that may help the problem. Thank you.

The problem started recently (perhaps a week ago), after one of the FIrefox updates. WHen I disable an add-on, after several seconds it re-enables itself. All of them, the same way, so it is not like it is a problem with one of them. I cleared FF history, cookies etc, still the same problem. I did not do any changes to the computer.

Hello,

I have had a few websites not work properly with Firefox and have needed to open my backup browser (Avast Secure Browser) to use those websites.

Right now it is FedEx that comes to mind again as I kept checking for tracking of packages shipped to me since receiving the tracking info. I queries consistently returned the error message "Unfortunately we are unable to retrieve your tracking results at this time. Please try again later."

Thinking maybe the website was having issues or maintenance (and forgetting I had the same issue with FedEx website the last time I tried tracking there in Firefox), I kept "trying again later".

Then I opened my Avast browser and pasted the same url there and, sure enough, received this report on the display:

Travel History Date or Time City & State Status Monday, April 18, 2022 9:47 PM SPARROWS POINT, MD Departed FedEx location Sunday, April 17, 2022 1:49 PM Shipment information sent to FedEx

I have tried disabling the extension NoScript as well as turning off the "Enhanced tracking protection" and allowing permissions for the FedEx site with no improvement.

I copied and pasted the RAW data as well as the text version from the "about:support" page to send you.

Any suggestions to fix this?

Thank you, Keith McNabb

Hello!

I have been using this userChrome.css code to hide the tab bar if there is only one tab (on Windows):

tab:only-of-type, tab:only-of-type + #tabs-newtab-button {

   display: none !important;

}

#tabbrowser-tabs, #tabbrowser-arrowscrollbox, #tabbrowser-tabs > .tabbrowser-arrowscrollbox {
   min-height: 0 !important;

}

Since one of the recent Firefox updates, this code does no longer work. Maybe because there is a new element in the tab bar: A drop-down list at the right.

Any idea how to make the above code work again?

Peter

Hi,

When using the right click menu on a PDF item in the Download Library (Ctrl+J) option Open In XYZ PDF viewer opens the pdf in chrome!!! option [selecting] Always Open In XYZ PDF viewer opens the file in chrome!!! option [deselecting] Always Open In XYZ PDF viewer opens the file in FF!!!

Double clicking on a PDF item in the Download Library (Ctrl+J) also opens the file in chrome!!!

This is totally wrong, please fix it asap. Thx
