Diễn đàn hỗ trợ Firefox

I have open half a dozen or so tabs related to one subject. I would like to put them all into one "super tab", such that only the super tab shows as an open tab. Then, by clicking on that tab, it would show the tabs within it, any one or more of which could be selected. Is this possible, and if so how is it done? Perhaps there's an add-on or extension that would do this.

I have already created a multi-tab bookmark that sorta, maybe accomplishes the same thing. But it's not as convenient as what I envision as described above.

Thanks for any advice or words of wisdom.

Hi, first of thanks for reading and possibly responding.

The issue I am having has been going on for a few days. In websites where youtube video's are embedded if I try and play the video on the said site it will load and display an error message An error occurred. Please try again later. If I visit the video on youtube, link provided in the video itself, then it plays just fine. Error is not restricted to one site but anything that embeds youtube videos.

I have also come across some strange youtube.com issues, when I am on the main website you get the thumbnails of video's but no time duration are displayed in the thumbnail, neither are the 3 dots where you can have one of the videos removed (not a big deal and maybe this was implemented a while ago I don't know tbh). When I play a video, as in visit the video page on youtube the side bar videos sometimes do and sometimes don't display time duration.

Please check attached image to see what I mean. Left is without said timecodes, right is what it almost should be.

What addons do I use: Ublock Origin is the only one worth noting but even without it the weird thing still occurs. I don't use any plug ins that correspond with youtube.

I am using the latest Firefox on Windows 10.

Things I have tried thus far to resolve it: - make sure Firefox is up to date - try with and without addblocker (Ublock) - remove Adobe flash entirely - refresh Firefox and clear all data and cookies 9tried this I think 3 times now, no change) - looked through older posts with similar issues but most links regarding html5 on youtube were 404 and sometimes the solution stated things like 'cause by some video helped addon' which I do not use or updating Flash

Am I the only one with this issue?

Dashlane Password Manager has been working as an extension on Firefox on my Acer Aspire E5-571 laptop, but for an unknown reason it has disappeared from my toolbar. When searching for 'Dashlane' on the Firefox browser to install the extension on my browser, nothing relating to 'Dashlane' can be foound.

Attached is a sample of how web pages display. These can either initially display this way or, as in this example, the page opened correctly, I stepped away for a few minutes and when I viewed the page again it looked like the example. I can have a page open and it is displaying correctly, then open a new tab and go to a different site and the text will look like the example.

I have cleared the cache, dumped all the cookies. Restarting the browser (I do this many times a day) will fix the current page but eventually another page will display like this.

I running version 84.0.2 64bit on a Mac Pro Mojave. I don't have this problem with other browsers like Chrome or Safari. I never see it on my Windows 10 system.

I've read some complaints about the font that FF desktop uses on some websites. I'm seeing a very annoying font with some letters thicker (almost bold) and other letters thin. This occurs, for example, on the mozilla.org website and when FF is displaying a PDF.

I have "allow pages to choose their own fonts" checked, and I am not using hardware acceleration.

I went into the developer console and turned off the Mozilla-supplied font for a support webpage, and it then used something like a Times New Roman, but it was uniform in letter thickness.

I have attached screen snips.

If I display the same page using Chrome, the font looks great, so I don't know exactly what the problem is, but it's clearly a FF problem.

Notice in Chrome that the word "garbled" is in bold, and it does not appear in bold in either of the FF font examples.

On 84.0.2 on OSx.

Firefox will offer to save usernames and passwords, but then does not remember them in the future. Attempting to import existing data from another browser into Lockwise prompts a request to set a primary password first. Attempting to set a primary password (which is currently not set), yields the error message "Unable to change primary password."

Just recently Firefox started to display a "Loading..." message in the middle of every page I go to in Breitbart.com (doesn't happen in any other website).

It appears about 2 seconds AFTER the page loads or press F5. The background goes dark suggesting it's modal. It lasts for about 1 second and then goes away and everything appears normal.

I've been told this is a Cloudflare anti-DDoS CDN protocol issue, but I'm not so sure of that.

I've started up in Clean Mode and get the same behavior.

TIA
