I believe with Update 154,0 my thunderbird has been freezing up. I can't see, to compress files or select some folders. After a few minutes everything freezes up. 21 AUGUST 2026

I went to my favorite web site this morning (dpreview/forums) and when it displayed I must have accidentally clicked some Firefox thing because the page was then overlaid with a thin orange highlight with the word PICK on it. I tried moving the cursor off the page but it only changed which segments of the page were highlighted. So I clicked and the page was replaced by just the menu section of the page, apparently that was what was highlighted when I clicked.

Now, no matter what I do, when I try to go to that url only the menu is displayed, the normal list of forums is missing. I've restarted FF. I've rebooted. I've cleared cookies and cache. I've refreshed the page. Nothing helps. Other web sites are fine. I can't imagine what this is for. A diagnostic tool or accessibility thing perhaps.

Please help. I'm running latest FF on latest Win 11.

When using any Microsoft 365 product on the browser I keep getting a prompt to "Please sign in" although I am already signed in. I can click the Sign in button and a about:blank page pops up for a split second. Then within a half hour or so, it will pop up again. I deleted my cookies but the problem still persists. Does not happen on other browsers.

Try to get "tvlistingszap2it.com" --(which I have been using for 5 years)--- but it opens "newsnation" Started doing this on 17 Mar, 25. What is wrong ?? Can you fix it ??

Hi, It is not a question but a bug report. From the version 131 up today the Nightly stopped to initialize quickly as before. Certainly, it is not the windows 10 21H2, the antivirus, the firewall or anything other similar internal problem, just because the Edge and the Opera are working fine and they are four times more rapid than the Nightly. It is just to say, that your procedures to improve the security is transforming the Firefox in a mirror of the usefulness Chrome. I take the time to open the home page of Firefox = 9 seconds, against 0.28 s of the Opera. So, I think you should rethink the security and other hidden setting options of the Nightly, because as is, it is very bad. The big thing that the Geeks from silicon Valley did not have in mind is: There are lot of people that need to find extremely fast a configuration, like to export/import passwords from older browsers, or computers, without need to replace one by one. There are many other things that you decided to hide, but I don't know why. Anyway, I will try to update one more time, then, unfortunately I could not use the Firefox anymore. Further, I want a few add-ons, either if there is any percentage of insecurity. A few times we need afford risks to understand and discovery other problems in the web. We cannot do it anymore with the Nightly.

Anybody. I'm ending up with dozens of tabs open because: 1. every time I hit HOME on my work tab, a new tab open up. One after another. It doesn't take long to have dozens of tabs open. Can anybody help me out here?

I'm unsure if this is a Firefox Mobile issue (since the site's login pop-up works just fine on my laptop that I also use FF on), or an issue with the website itself, but I've already emailed the site about it and got no response yet. So, figured I'd try here. Also, I just tried re-enabling Chrome to truly see if this is browser or app related and sadly this works on Chrome's Mobile but not FF's.

On the mobile and desktop version of this site: thingstogetme.com

There's an option to login with Facebook or Apple ID. The Apple ID pop-up works fine, but the Facebook one does not. Again, this is only an issue on Mobile. The Facebook option will turn a darker blue once you tap on it, indicating it's been selected, but nothing will happen. If you tap the page, it'll go back to its regular, un-selected blue.

I've turned off uBlock Origin, switched between mobile and desktop pages, refreshed, nothing works for this problem. Thus this essentially soft-locks me out of this site unless I use my laptop.

Thunderbird 147.0esr Email arrives. I open it It has the usual 'view this thread' link I click that link waterfox opens all of my home pages.....not the email I have disabled all add ons, in both thunderbird and waterfox....I have changed profile in waterfox & synced with firefox.

Hi, I have an HTML page - currently on the desktop PC - that contains a few graphics (they relate to IPA sounds) and a bit of javascript which will make the sounds play when the user mouses-over the graphic, and stop on mouse-out. The script uses <embed> tags. I know these arent favoured but I think they should still work, as they have in the past, so the script itself is fine. But there is no sound (obviously I have checked the src is correct and made sure the speakers are on and working. They are.) W10, FF ver 128.6.0esr (64-bit)

This is observed on Pixel 9 Pro. Running Thunderbird v21 from F-Droid.

Not sure if this is in the latest update, but if I select a message, the top of the screen (where we are notifications and battery level) turns into a black bar. This happens in, both, the unified mailbox and a specific mailbox.

Is this a bug or normal behaviour?

During what I assume are high bitrate sections of YouTube videos (e.g. lots of movement, high resolution) YouTube will constantly drop frames.

Video for example: https://www.youtube.com/watch?v=KLuTLF3x9sA

I have tried: • Safe Mode • Installing the Flatpak and testing in that, which also has a fresh profile as I don't use the Flatpak version • Testing different related about:config settings – I can't remember them all now, but I tested every one I found googling that is related to the issue or hardware acceleration.

Hardware acceleration is for sure working. Turning it off makes the video drop to one or two FPS.

Chromium has no problem with the same video. However, you can see from the screenshots that both read the resolution/scaling of my screen differently, and it implies that Firefox is rendering something like 6314 x 3552 while Chromium is rendering at UHD, the resolution of the screen and my video. If I turn off all my Global Scaling, Firefox stops dropping frames (the same info box on YouTube states resolution is UHD), reinforcing my theory about scaling being the issue. Both are confirmed to be using native Wayland.

Unable to use Firefox to access Youtube. Problem started either late last night or early this morning. Whether using a bookmark or entering "Youtube.com" manually, the browser window merely acts as if I'm not even connected to the internet before finally just giving up.

Have tried using both 115.17.0esr (64-bit) and 132.0.2 (aarch64) versions of Firefox (each using a different computer), but YouTube refuses to load.

By contrast, YouTube has absolutely no problem loading using other browsers, the site loads almost instantly.

Hi, tbird 128.3.0 esr 64b w11p. A prob new to me. Only for MS outlook mail (aka office365 email, but no ofc365 on my laptop, just the email in tbird). -in unified folder view, my MS mail acct (it still has the "hotmail.com" address, but works), is not present -- that's the problem. A workaround is that I can choose both "unified" and "all" views together -- but while the MS mail acct now appears in the folder pane at the top, as well as in its own "place" at the "accounts" area below, that MS mail acct not longer has its messages appearing in the "message list" pane. I have to go to MS Mail's own place below, in the folder pane (as stated above),to see its msgs. in msg pane.

 I could use the "all" view, but it's not as nice & I never have had to choose that before this prob.

- I did run "repair folder" for MS mail's own inbox (again, below, in its own place below, in folder pane, accts). And I restarted t-bird.No change in behavior, unified view does NOT list my hotmail emails.

I have used & am comfortable w/config ed, but only when I have the proper instructions you may post in your potential reply (I am not a coder).

Please advise, thank you.

I have a Dropbox Paper document that I use for my bookmarks. It lists the name of the site (with link attached) and hints as to my username/password for any given site I use.

For years, it has worked just fine, but trying to solve a different problem, something happened (in my settings?) that renders those hyperlinks non-working. When I click on, say Facebook, it formerly took me right to FB. NOW it gives me a weird yellow box in the upper right corner that says "about:blank" in the upper left of the box, and 3 white boxes at the lower right of the yellow box "Allow" "Deny" "Close." If I click on "Allow," I get a blank page. My navigation doesn't seem to recognize the links I've placed in the Doc.

A friend on FB posted a link to a YouTube video and when I clicked on that, I got the yellow box with the proper URL and a white box option to continue. I've tried to recreate that particular box, but, apparently, once it's accepted, it's OK from there on out.

I have tried deleting the link from the Paper Doc and reinstating it, and I still get the yellow box.

What have I done and how the heck do I get rid of that yellow box?

"The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can caused this problem".

How do I resolve this problem?

I posted a question on this forum that I want to delete. I can't find a way to do that. Is there some way to do it? This question isn't really about performance" of T-bird, but about this forum but I was required to make a selection. . . ..

Good Afternoon,

I bought a guitar course from this web site, https://masterclass.davidleviguitar.com/users/sign_in, and whilst the page opens up, when I click on any part of it nothing happens.

I then downloaded Chrome and everything works perfectly.

Can you please tell me how to get this site working properly on my computer, as I don't want Chrome on my computer.

I thank you and look forward to hearing from you.

Kind regards.

Greg.
