I am facing a issue recently in firefox that I cannot see the page contents correctly. Couple of examples : - when I open youtube.com, dont see the video thumbnail images. I see blank there. I can see the video description though. But when I click on a video link, it plays okay. - Some webpages are not rendering correctly even when there is no video.

I tried following, without success - - uninstalled and re-installed firefox - opened firefox in safe mode.

I dont have any extension. I have shockwave plugin installed. And the OS is Windows 10

The search boxes in the inspector window window returns no results whenever I try to search for specific key-value pairs like: role="main".

I can only get results for main or role. Is there a search string parameter/syntax reference anywhere? I've searched high and low, but articles/references found in the documentation is VERY basic.

Thanks

I've been unable to restore bookmarks after allowing Firefox to speed things up? How can I find them?

I followed the instructions and got the message: "Unable to process the backup file." I really need my bookmarks! How can I restore them?

I watch General Hospital online and it was working fine until the last update, about 2-3 weeks ago. Now the episodes will not run. I have tried running the browser in "Safe Mode" and turning tracking off, as suggested, but neither of these worked. Please help.

Firefox 63.0 x64 not preserving window size and launches taller than screen size

I've tried deleting the xul file and other recommended solutions.

I have both bookmarks and command toolbars enabled.

Display is 3840x2160, Microsoft Windows 10 x64 has Display Scale and Layout set to change the size of text, apps, and other items at 175%.

Launching Firefox will always launch the window taller than the screen height (2160) having the command bar above the top of the screen and the bottom of the browser below the bottom toolbar.

Resizing and then quitting and relaunching will launch Firefox at resized window size. Firefox settings are set to remove all cookies and cache upon exit. Exiting with File->Exit or clicking the top right X both seem to work.

After some period of time, typically after a screen lock or reboot, a new launch will revert back to the old size that goes off the screen.

I need to figure out how to make the resize sticky.

I did not know where else to go, the "Volunteer" button brought this direction. What things do I need to know for testing? I have manually tested web-based apps in Quality Assurance for two years, but no real coding skill-set as of yet. I figured I would learn more by volunteering, but there are so many options. I would appreciate the basics cover across the board for starters. Thank you

Recently, if I want to log into websites that require passwords, every time I open Firefox, I have to go to Options > Privacy & Security and RECHECK the box for "Ask to save logins and passwords for websites," which is now unchecked every time I open Firefox. I can't find a way to have the box stay checked session-to-session. This is a recent development and, I suspect, is related to the "upgrade" to the latest version. Is there a fix?

I was running Firefox beta and suddenly the minimized pages would not restore to their previous sizes. I uninstalled Firefox and installed the new version from the web site. All bookmarks, history and passwords were updated to the new install, however nothing appears on the tab, not ever the Firefox home page and none of my bookmarks work. There is simply no link. I am running Windows 10 (32 bit) and have a vpn. I am using Chrome to contact you, but would like to go back to firefox asap. I use my computer for work, and cannot be without it.

Hi. I just noticed that my browser had auto-updated itself to version 63.0, and now, videos on Youtube and news sites auto-play, even though I have it disabled in About:Config. Until today, all html5 videos were being blocked just fine by that setting. Why is this happening and what can I do to re-block videos from auto-playing?

Some web pages like LinkedIn for example show a dark solid red background with black lettering.

I tried installing a theme and changing the settings in Firefox.

Opening the same pages in Chrome, they are normal and not red.

Could not find any articles on this other than ones pointing to themes.

Thanks,

A few days ago, I was testing a dark theme related add-on, but since uninstalling it, have had this issue where my theme seems to be stuck as the Dark theme that naturally comes with Firefox. When attempting to change my theme in the customize window, mousing over the Default theme does show the proper colors for it, but selecting it still shows the Dark theme colors. I tried examining my Add-ons manager, where it shows that I am still using the Default theme, despite the colors clearly belonging to the Dark theme. I can freely change to the Light theme without issue, but for some reason, the Default one refuses to load properly. I have since tried uninstalling all my Add-ons, deleting my profiles, and uninstalling Firefox before restarting my computer, but to no avail. The Add-on I was examining initially was the Dark Night Mode add-on. Examining the page info, it does say it is not perfect, and their home page says that there are complex issues with getting it to work with Firefox, but I was unable to find more information on this offhand, nor any descriptions of scenarios like mine. I believe the initial settings for my Default theme came from some setting based off my color scheme I have set for my computer themes in general, based off my background, but I was unable to find more information on this at the time. The screenshots I am including are of my Add-on manager showing that I am using the default theme, the customize menu showing the Default theme when highlighted in the drop down menu to change it, and the result that displays when the Default theme is selected. Any ideas on why this issue is occurring, and how to fix it, would be appreciated.

If I deselect OCS option in Firfox parameter the issue disappear but come back when I select again the OCS option. How this issue can be solve definitively with keeping OCS option ? Is the connection as well secure without this option ?

Latest Firefox 63.0 OSX High Sierra 10.13.6 (17G65) - no antivirus scanner - not on a corporate network - no proxy servers in Firefox or OSX

These do load without problems: https://www.google.de/ https://www.google.at/ as well as any other website I've tried

What I've tried so far: - Safe Mode - Firefox Refresh - complete removal of Firefox and profile, re-download, fresh install - switching between wifi and cable connections

No other browser on my system has these issues, testet with Safari, Chrome, Vivaldi

I do remember having this issue on 62.0.3 too...

Thanks for any pointers.
