Форум поддержки Firefox

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?

On this site: https://www.orange.pl/twojekonto/zaloguj I can't force firefox to remember username (no problem with remembering password on next step). In older Firefox without WebEx there was addon which allowed to manipulate forms to prepare proper autocompletion data. This addon is not supported with WebEx anymore due to lack of proper functions. Instead Firefox Dev Team claims that mechanism built in current Firefox is enough for such tasks and mentioned addons are not needed. Seems it is wrong thinking.

I tried different approaches to save username for mentioned site but without success.

Hello, I have downloaded Firefox installer but I couldn't install it. It's giving issue that you need to start over but when i start over again it gives the same issue. I have some pending work to do on my blog so I nee to install it ASAP. How can i fix it? Please help me. Thanks

Well this happened after a Firefox Update with that i also suspect that using a User.js can aslo cause it would you like to look for the problem pls.

```js // /* You may copy+paste this file and use it as it is.

*
* If you make changes to your about:config while the program is running, the
* changes will be overwritten by the user.js when the application restarts.
*
* To make lasting changes to preferences, you will have to edit the user.js.

When using Waterfox and I am trying to stream video content through my HDMI port to a Vizio TV, I encounter a variety of issues. 1) The audio content comes across but no video (black screen) (The most common issue) 2) I can sometimes get the connection to work by starting the stream then plugging in the HDMI connector rather than connecting with the stream paused. 3) Twice, I crashed Windows (Win7) by unplugging and plugging the HDMI cable in while trying to get the thing to work. That is not something I would want to risk again unless some possible bug is found and removed first. All extensions were disabled and I was updated to the latest Waterfox version. The sites I can't use are PBS Passport and The Smithsonian Channel for sure, but I never tried YouTube out of fear of creating another system crash. I tried moving to Waterfox because I liked the speed and many of the features, but I had used Slimjet (64 bit) for years and have never had this HDMI interface problem.

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 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.

I am using Firefox 108.0.2(32bit) on a Windows 7 computer. Within the last three weeks two sites Menards.com & aarp.org have become blocked by security rules: Menards by Incapsula & AARP by Imperva. All other websites I currently visit work fine as did these before. I've cleared cache and cookies and "forget these websites" in history. This solves the problem for the first page on Menards.com but any link-click and the problem returns. This also cleared the AARP website but I cannot log in to my account there nor access some of the other clickable links. I can access these websites fine on other computers on this network using Firefox. This computer will access those two sites using the portable chrome browser but not the installed Tor browser. This computer will not access these sites using a VPN or with AVG disabled. I've toggled a few DNS and HTTP settings with no effects. For a year, the only thing I noticed different from this computers and the others is that this one continues to allow Java to be updated whereas the others are unable to download its update. Could that be the problem? Why these are the only two websites that seem to be affected is the baffling part. Menards has thanked me but has not gotten back and AARP wants me to reinstall my operating system. Thanks for any help you may suggest.

Firefox began returning a PR_CONNECT_RESET_ERROR error on all websites a few days ago. Chrome likewise. MIcrosoft Edge is working fine. I am running Windows 7 with Kaspersky. I tried turning off the Windows Firewall and the Kaspersky protection, but it didn't help. I also tried disabling plugins, theme, and add-ons but it still didn't help. Any suggestions?

I had two Firefox windows open. One had 100+ tabs open, the other had around 5 open. Like a klutz I accidentally closed the window with the 100+ tabs open instead of the other window. Now when Firefox restarts it opens the version with the 5 tabs.  :-( I read about lost tabs in Firefox. I have found a file with the 100+ tabs in it. It is called: upgrade.jsonlz4-20221007134813. But what do I do next to restore Firefox to restart with the 100+ tabs version? Thanks.

I am under a disaster with todays mess of firefox, even on chrome now to try here to get some help. I am having to redo my pc OS etc and I am needing to swap over my app data to the temporary backup pc. I know how to do that but it won't even let me start firefox as it is an older version. I install a newer version and that is one of the new version disasters I hate. I have no time to figure out how to make it look to where it is usable. I got the old pc running and found the version it had. I install that, which is an esr but it still gives me the same problem. I need my firefox working so I can use it with my original tabs and bookmarks. Or you can be like some and tell me to just go elsewhere as a fix for the mess which is todays firefox. I used to have about zero of these kind of problems. How do I get myself to my original setup on the temp pc?

I can't for the life of me understand what is going on with my browser. Everytime I try to watch a video that I have purchased I get this error message:

"Firefox is installing components needed to play the audio or video on this page. Please try again later."

I have tried searching for a solution but no avail. I have disabled and re-enabled DRM, bit it was a no go. I tried re-downloading firefox, still had the same issue. I created a new profile, still won't work! I have been searching for solutions constantly and tried so many but none seem to work. Finally someone suggested that I check my extensions and App data and I saw a sign that said:

"widevine decryption module provided by google inc. will be installed shortly"

but it has been almost a day and it still hasn't been installed. In advanced preferences I looked up widevine and saw this:

media.gmp-widevinecdm.autoupdate true media.gmp-widevinecdm.enabled true media.gmp-widevinecdm.lastDownloadFailReason Error: Failed downloading via ServiceRequest, status: 0, reason: error media.gmp-widevinecdm.lastDownloadFailed 1671609470 media.gmp-widevinecdm.lastInstallStart 1671609449 media.gmp-widevinecdm.visible true

Is the problem with my computer or internet?

Dear sirs,

I've got the latest English (US) version of Firefox 108.0 from this website. The problem is with Windows crashing in few seconds after Firefox is launched. Although this trouble appeared yesterday (maybe after the automatic update of FF - I'm not sure).

Please advise any solution ASAP!

Windows 7 Home Extended SP1 64-bit. Now I'm using another browser to write this message.

I updated to new version 108.0.1 (64-bit) and found: icons for my extensions disappeared. Extensions exists and turned on, but toolbar don't show them. How can I restore them?

Radmir.

When I load Chargehub.com into Firefox I should be able to see icons for electric vehicle charging stations plus a menu for such things as plug filters.

However, although the chargehub site loads with a Google map (after selecting Map) I don't get the EV charging station icons or menu. I do get POI icons such as for airfields, cemeteries, parks, churches, etc only when fully zoomed in. The Google zoom symbols and street map view options are also available.

I have not experienced this issue on any other WEB site including Plugshare or Chargemap. Further, when I open Google maps in Firefox and do the search, "ev charging stations in ontario canada", i do see the icons for charging stations.

I am running Windows 7 with Firefox version 107.01 on a desktop computer. Adblock and uBlock origin are installed. However I have the same results when running Firefox in safemode.

I do understand that Microsoft no longer supports Windows 7. However, my son is also running Windows 7 on his desktop computer, yet chargehub opens properly on his computer when using Firefox as his browser.

I've tried searching the WEB for an answer but no success so far.

Thank you in advance for any help.
