Since ± half october 2018 I can't play videos anymore on some sites and get this crash message. Youtube does work, probably because without Widevine? I'm on FF Dev Edition, Mac with El Capitan. Thanks, Pieter

So how exactly is firefox supposed to work with oculus rift?

If I click on the vr-button on https://aframe.io/a-saturday-night/ it just makes it fullscreen on my main monitor.

If I click the vr-button on a video it usually tells me to get a browser that supports vr.

I am using Firefox 64.0 on windows 10 desktop.

I know this question has been posed more than once in the past. The answer has always been: go back to school, learn computer programming, get master classes and practice with coding until you make it. I am using Watefox since when Firefox tab bar was moved close to the sky. I just decided to try Firefox again: I have installed it and the first thing I tried to do is moving the tab bar below the address bar. It seems that there's no easy way. How can it be?, I wondered. With Waterfox I use the Tabs on Bottom add-on and that's it. You may believe my need is frivolous, but for me that makes the difference between keeping or uninstalling Firefox. Bottom line: is still forbiddend to wish to get the tab bar where I believe it should be? Thanks,

I know how to bookmark a page- what I want to know is how to restore the bookmark star in the address bar (I accidentally removed it). I KNOW that you can bookmark a page by clicking the 3 dots at the end of the address bar and using the drop down menu, etc, or key commands.

BUT- I want to RESTORE the star that easily and quickly allowed you to bookmark a page. All other answers to this same question seem to only tell people alternate ways to bookmark a page. I don't need that. I need to know how to restore bookmark star to address bar. Thanks!

I ran 2 different versions of Linux Firefox from a Linux CD and Firefox version were not able to play HTML5 from Youtube. Youtubes test shows HTML5 not available. The version of Firefox was 61.x

Why would it not play as I expect HTML5 in to Firefox? Linux support seems to think a update is required but that should only occur if Firefox itself is dependent on the operating system.

There used to be a button in the toolbar which let you see the RSS feed for a site, then it got removed but you could add it back through the customization menu. Now I can't seem to even do that.

I guess that Firefox used the RSS button for its live bookmarks feature, and since they removed the live bookmarks they seem to have also removed the button? I only ever used the button to get the feed addresses though, so I could paste them into my RSS reader. So... if I could get the button back it would be great. Otherwise, maybe there's a plugin which does the same thing?

I've been watching videos on my Amazon Prime account for months using Firefox without an issue. As a matter of fact I use Firefox exclusively because the quality was better than on Google or Edge. I haven't watched any videos for about a week, busy with other things and decided last night, with the snow, was a good night to watch a video. I clicked the Watch Button as I have for months and the icon went around and around and around. The video never started. I tried 3 more and none of them would play. I called Amazon they had me clear the cache and cookies, and it started to play, I stopped it and said it looked like it was fixed and hung up. Went back to play and the icon went around and around etc. The videos play fine in Google and in Edge no problem with either of those browsers but still not playing in Firefox. I checked and see that Firefox Updated since the last time I watched videos on it. I read some articles that suggested I remove Firefox from my allowed programs through the firewall, then re add it. Did not, no improvement, the videos still will not play. I wasn't sure if their videos were Flash or HTML 5 so updated Flash... nothing they still won't play.

Any other suggestions?

I tried up upload a screenshot showing the date when FF Updated, but it seems it's not working... dated updated says January 9, 2019
