Firefox Support Forum

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?

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 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.

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 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.

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.

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.

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.

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 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?

I am using DuckDuckGo with Firefox because I do not like auto suggestions filling up the search bar while I type. It's so annoying. I have ensured that Settings do not have auto complete in any way, but still they come. The only solution I can find on this website, which is Stop Auto Search in Firefox

There is a preference to change that back, but it does take a bit of work to find it because of the unusual name: (1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk. (2) In the search box in the page, type or paste handoff and pause while the list is filtered (3) Double-click the browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar preference to switch the value from true to false Success?

I had no success with it at all. Please, how can I stop this wretched feature? Thanks.

Hi. I want to sync with my work pc (it used to work just fine but when I synced to a newer third pc- successfully- it just stopped). When i try to sign in on the work pc it asks me for the primary password which it then FAILS to recognise to allow me to proceed! What's going on? I can't even log onto sites with saved passwords anymore. Any help appreciated.

I recently moved from a Firefox fork that supports Classic Theme Restorer to one that doesn't. Sigh. It was however a relief to discover that I could make most of the same UI changes myself with a bit of effort. The only major customization remaining is a traditional "page loading" animation in the right corner of the address bar, preferably a swirly or moving dots animation and not the hourglass or ping-pong dots. How is this do-able with current builds? Thanks.

Not sure if this is the best place to ask, but when I try to take a document from one place and try to insert it into another document, hitting Crtl-A, Ctrl-C or -X to cut it from Doc 1 then hitting Ctrl-V and pasting it into Doc 2 wipes out the margin setting arrows so I can't change the margins to match Doc 2. And my attempts to get around that screw up the formatting of the document. Any suggestions? Thanks.

When I go to recent bookmarks list in firefox and select one, firefox is vectored off to paydaydeals.com I have right click the bookmark and looked at the bookmark details and they look fine. I have check add-ons and extensions none are listed as installed. How is firefox being vectored off to this site? See screen shots. I have scanned with Malwarebytes latest version and Eset online scanner no bugs found.

How can I fix this?

thank you ashley

The web page, for my bank, won`t open. I have been using their web page, for a number of years. When I go to the web page, and try to login, all I get is a screen, with a circle, that keep circling, as if it were buffering, and never gets to the login page. Microsoft Edge, and Google Chrome seem to work, but not Firefox. My bank is Security Bank Of Kansas City. https://secure.securitybankkc.com/login

The little image shown will appear and float on the left bottom of pages I open including secure pages that require me to log in to enter. That little stick man I consider a security threat and have tried to get rid of it to no avail.

The picture I captured of it was when it was on blue background. If on white background, just the circle with the stick man in it.

How can I delete it?
