Firefox Support Forum

A required site I need to use for work has a popup dialog box that never works right in Firefox, the popup dialog shows up as a blank box or doesn't popup at all in Firefox. I must print what is supposed to be there in that dialog box. It's been like this for a couple of years now. I've tried everything imaginable and searched high and low for the fix. I have had this particular site set as an exception to popups blocking, and then I also set it to have all popups unblocked. Still doesn't work either way. I have to use the site in Brave instead, and it's the only way I can get what I need done. I used to love Firefox SO much, I used it exclusively. But it has undergone some unpleasant changes recently, such as hiding my open tabs on my iphone. Because of these issues I find myself using other browsers more and more.

FireFox V. 107.0 -MBP-High Sierra.

Lately the last couple of months when I google search webpages then select them, Fire Fox doesnt bring up the article, Its been happening a lot and getting really irritating. So I bring up Google Chrome and it always brings up the article. SEE THE PICTURES. I use only Fire Fox as my browser, I keep Chrome around for when Fire Fox doesnt want to work properly. As you will see in the pictures the same website for both browsers. Fire Fox wont show the article no matter how many times I refresh the page or shut FF down, or reboot my MBP, but Chrome works perfectly every damned time. Why cant Fire Fox open the article but Chrome can? I need your help, any advice is greatly appreciated. SEE THE PICTURES.

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

Clicking the mousewheel still works, but scrolling doesn't work. This behavior occurs on tab bar as well.

Using option "Restart with addon disabled" from about:profiles can make the mousewheel scrolling work, but manually disabled all addon and restart just won't solve it.

Firefox 114b5 does not remember form history. I have tested two different websites.

I have form history enabled - see attached browser_settings.png. Attached is a screenshot of the moz_formhistory table in the formhistory.sqlite file.

What do I need to do to enable form history on all websites?

Buttons like 3 bar preferences button, notification etc are broken or not visible just the highlight is visible and click the notification button also break the whole browser

Firefox beta release: 116.0b6 (64-bit)

On sites such as BBC.com, Youtube.com and Facebook.com I am not getting the normal cookie consent pop-up option which used to automatically show on opening the sites. Other sites are still showing the cookie consent option pop-ups. This means I cannot select if I wish to accept or reject cookies on several sites that used to allow me the option.

In checking about:config, the cookiebanners.service.mode is set to 1, which I believe this the correct setting for enabling the cookies consent pop-up option.

Is there any fix for the cookie consent pop-up not working on certain sites within the EU? I am not using a VPN or pop-up blocker. Tracking protection is set to Standard, cookies and site data are always deleted on closing Firefox and "Do Not Track” signal is set to always. Deleting all installed FF extensions has no effect either.

In other browsers on the same PC, Chrome and Edge, the cookie consent option does still work as it should on the sites mentioned. In Firefox it doesn't.

This is only happening on one PC. My latop has the same FF beta build installed and is not showing this behaviour, it still automatically shows the cookie consent pop-ups when visiting sites such as BBC.com, Youtube.com and Facebook.com.

for new file types the option to save the default behaviour for future downloads is no longer avaliable for me. Also, the option to set in "Settings -> General -> Files and Applications" does not show any of the new file types.

I've tried re-installing firefox, as well as refreshing but still the same results.

I've got a new computer I am setting up from scratch, and though I have set FF to sync settings, I'm still having to customize a lot. My bookmarks toolbar is crowded again with icons and I'd like those to go away. I don't mind other icons staying around on the tabs--that does help me navigate faster. I had this set up before, but lost the setting when I refreshed Firefox.

Hello, I have issues with Firefox developer version for couple months now, when I play videos, like youtube, or other sites they constantly lag. They play for like 1min and lag, continue for another 2min then lag etc etc. (even short videos on twitter lag). It was not like that before and I don't have this problem in other browsers. Does anyone know what can be the problem here? Thanks

After updating to version 94.0b9, the program began to slow down terribly. This is especially pronounced on YouTube: you select a search, enter a request, open two or three tabs from the proposed one with a possibly useful video ... That's it! You can go to a cafe for coffee and rolls. It became impossible to use the browser.

How to roll back to the previous version of the program?

I'd swear that I used to be able to click on an animation/video/gif to stop at looping, but I cannot stop this one by doing that:

https://d2rdhxfof4qmbb.cloudfront.net/wp-content/uploads/20190129121540/facts-min.gif

It must've been one of those custom settings I had before I got the new computer and ran a clean install of firefox.

I have set media seamless looping to off in about:config, but I can't see what other preferences would relate to this.

So, certain web pages apparently have text in white font color while also using a white background. I'd blame it on the team behind the page, but it seems that it works well on Chrome, so I'd like to know how to fix it.

I'd add images, but they take way too long to upload

Hello,

Since the last firefox update to version 97.0b3 a new "effect" appeared, which is truly annoying. Whenever I download something, the downloadbutton message pops up, and I don't know how to get rid of this. Could you please tell me how to change the settings to prevent this from happening?

15 january 2022

Thanks in advance, Alicia

After installing the beta FF 98.0b3 in order to work around the Webroot problem currently going on with v97, I've noticed that whenever I download something, the download popup window stays active until I click on something. I don't want to remove the download button because I want to monitor download progress, and at times, I DO want to look at specific downloads from time to time. But the fact that the window automatically pops up and stays there until I click on something is annoying.

I saw similar posts several years old about older versions which don't apply now.

So, is there a way to disable this thing without completely removing the download progress indicator from my toolbar?

Thanks again for the help!

I have tried all of the about:config options to disable the auto-reload of the tabs. I have this working fine on my old machine macbook pro 2015 (same firefox version), but on the macbook pro 2019 i cannot get it to stop. Any help would be great as I need to switch between tabs during meetings and dont want them to keep relaoding

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

Ver 100.0 Settings:Startup:Open previous windows and tabs is UNCHECKED. But every time I open Firefox, it opens the last site I had open before I closed it.

This worked before ver 100 and suddenly has stopped working with ver 100.

I even rebooted the computer (Win 10, 64-bit) and same behavior continues.

Hello,

Whenever I use Firefox, I end up seeing popups (necessary for school) and would like to show them as tabs so I can merge them into other windows. I have tried the solutions given in: https://support.mozilla.org/en-US/questions/1080255 and nothing seemed to work. Is there another way to make sure that popup windows cannot hide the toolbar and show tabs?

Recently, I've started noticing these quick action tiles in the URL drop-down menu (I've attached a screenshot). There's a help icon to their right, but it just goes to https://support.mozilla.org/en-US/kb/quick-actions-firefox-search-bar?as=u&utm_source=inproduct which is a 404. I found this bugzilla bug, but I'm not 100% sure on how the versioning works (even after consulting Wikipedia). The bugzilla entry mentions it's fixed on 105.0a1. I'm using 105.0b6 of the Developer Edition.
