Firefox Support Forum

I have a problem where if I install the packages needed to get hardware video decoding working in firefox it completely breaks YouTube playback. I can't find any info on the internet about the problem and I am having a lot of trouble with it. YouTube playback with libva-mesa-driver and libva-vdpau-driver will start stop restart start playing audio then crash with a this error every single time. I am at my wits end trying to figure out this problem and I would love help figuring out the problem I am using firefox-developer-edition as a note thanks Ozzy

I've been seeing the black embed icon appear when I select text. It's only been recent. My browser is 125.02 and up to date and I have Windows 11.

Is this from a recent update? I'd like to disable it if possible.

I attached a screenshot.

Thanks in advance!

Sorry, posted recently and had then trouble finding out how to respond to help offered (jscher2000)! Noticed that the email version was "no-reply" so I didn't figure that would work! So, I tried to 'cut and paste' my reply (on a smartphone) and I ended up losing even the email reply text so here is a reconstruction. I tried the suggestions in order and the first one didn't have a "Restore previous session" option and the second one had "Recently closed windows" greyed out! And, when I entered "about.support" in the address bar (top rightish), I received a notice that I couldn't reach Google (Remember that I don't currently have internet access on my laptop). So, no joy there either! Can I not just change some current setting to prevent Firefox v 115.9lesr from saving the current 'Windows' and Tabs so that, when I again open Firefox, the previous session 'Windows' and Tabs would be used?!?

I can open the Chase bank site, but cannot log into my account. I can log into my Chase account using Edge. This may have happened after the most recent update to Firefox. Any ideas how to fix this?

I am trying to log on to my account at SketchUp. At the login page i hit get started and a black page come up except in the top left corner is typed "Firefox not responding" the page hangs a few moments then it takes me back to SketchUp login. I have not had any recent updates done or required since last logged in and that was yesterday all worked well.

Here is the extension i would like to convert

How do I fix?

Thanks for any help!

I don't want to be able to scroll the page by selecting text. That's what the scroll wheel is for. More often than not this 'feature' just results in frustration as scrolling the page selects more text. Can I just disable this altogether somehow?

I made a small CSS customization to my tabs in FF 115 ESR on Windows 7, so they would be flat on the bottom and rounded on the top, looking a bit more like tabs instead of buttons.

Looked ok in FF 115 ESR.

However, in FF 125, half the tabs are now cut off, including their text (see attached images).

Also the tabs background is darker in FF 115 ESR, providing more contrast between the tabs and the tab bar. In FF 125, it's almost all white and I can hardly distinguish between the tabs and the tab bar.

Why is there such a big difference in appearance between FF 115 ESR on Windows 7, and FF 125 on Windows 10?

Here is the code I used...

/* ------------------ RESIZE TAB BAR ----------------------------- */ \#TabsToolbar { height: 27px !important; margin-top: -1px !important; margin-bottom: 0px !important; } \#tabbrowser-tabs { height:25px!important; min-height:25px!important; }

.tab-background-start[selected=true]::after, .tab-background-start[selected=true]::before, .tab-background-start, .tab-background-end, .tab-background-end[selected=true]::after, .tab-background-end[selected=true]::before {

 min-height:25px!important;

.tabbrowser-tab {
 max-height: 25px !important;
 border-color: #8f939e;

 max-height: 25px !important;
 border-color: #8f939e;

} /* ------------------ TAB HEIGHT END ----------------------------- */

I inserted backslashes at the beginning of the first 2 lines of code above to preserve the hashtag sign (otherwise it displays an index number before those lines), please ignore the backslashes.

I would like my customizations in Firefox 125 to look like the ones I made in 115 ESR.

Is it possible?

Thanks!

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

Hi. Strange request I know because Firefox is working perfectly but Google has failed me.

We have a printer/copier in our small club. The IP address assigned is 192.168.1.125. Typing this into a browser should bring up the copier admin dashboard.

When I do this using Firefox everything works fine, BUT when I use any other browser such as Chrome, Edge or Opera I get the "Cannot connect" "Error connecting" etc message.

I removed Bitdefender antivirus and disabled Windows Defender but it's still the same.

Any network people who can point me in the right place as to where to look or report to the correct forum.

Apologies for posting in here when it's not a FF problem.

Thanks in advance TQO

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

Hello,

 One of my email accounts Yahoo or Gmail appears to have been hacked. I received two phishing emails this week --3 if you count the last one who said she was calling on behalf of Medicare/Social Security and All members could get a preloaded card for several hundred dollars. I knew there was a plan to help certain folks, but it was not available to everybody. I asked her for the name of the plan and she hung up. the webpage she sent me to first or told me to go there where I could talk to a licensed agent. Do people who answer the phone have a license like insurance salespeople? Anyway, they had copied the govt. the site is right up the US sea.

Okay, just an example so I decided to try that KeeopassXC program you were offering but I could never get it to complete.

but it did something as I can't use my password They cancel your account if you tell them the truth --better just to say I need help resetting my password. They then ask you to send them a picture ID as in Driver's License. Noway I am going to do this --so I have at least some pretty valuable info if I can't get in.

Ny first time writing here - if any response please direct suggestions to pke225x2gmail or I guess I will check here. Don't know how you put people with possible solutions to seeker of HELP.

Sincere Thanks Paul

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

Am trying to update my email address. When I try to make the secondary the primary, it wants a verification code entered. The field for this code will not let me paste it or enter it manually. Will this glitch be fixed soon?

Others asked and were pointed to extensions. As long as extensions get access to my pages, I'm not willing to use any. So, is there an option in advanced settings, to return to previously viewed tab when I close a tab? Thanks, Cat

I am a Salesforce (improveit! 360) user, exclusively browsing with Firefox for over 12 years without any problems. The most recent Firefox update 125.0.2 (64-bit) has caused an issue with my staff calendar. I have reached out to improveit! 360 they are a force.com developer and they will not help, said the error is caused by Firefox interpreting the code. I have figured out a work around to get the calendar to load correctly for a short term solution. Below is a screenshot of the error, any help would be greatly appreciated.
