Forum zgromaźeństwa Firefox

I'm using Firefox, updated to version 140.0.4, on my Windows 11 laptop. Since Edge is my primary browser, I normally only use Firefox for two particular websites that don't work well in Edge. Beginning in March 2025, I've had a strange problem with one of those websites. In certain situations, words or phrases pop up in text boxes, meaning that if I want to type something, I first have to delete the word or phrase. Since it's a game website (not a video type game -- actually contract bridge) and the game is somewhat time-sensitive, this is very annoying. The words and phrases are ones that are appropriate to the website (i.e., not random), and seem to be the same in each session. That's why I labeled this as a "clipboard-related" issue.

Clearing the cache seems to help for a short time, but the problem always returns. <Ctrl>-F5 also helps, but seems to work for some text boxes but not others. In fact, <Ctrl>-F5 works for one type of text box, the type that I use most often, for the remainder of that session. But if I use one of the other text boxes, it doesn't help.

If that isn't strange enough, there are two additional oddities: For the other text boxes, the ones that are unaffected by <Ctrl>-F5, if I continue to use them, they eventually stop popping up words and phrases, again just for the remainder of that session.

The other oddity is that I'm using the free version of the LastPass plugin, and every time one of these words or phrases pops up, the LastPass symbol (a red box with three white dots) also appears at the right of the text box. This is completely inappropriate, since these text boxes have nothing to do with logging in or passwords. For this reason, I'm going to try to contact LastPass to ask about the same issue. However, their support isn't very responsive, so I'm hoping that somebody in the Mozilla forum will have a solution.

As I said, the problem only occurs on this one bridge website, and although I've been using Firefox to access it for several years, the issue never occurred before March 2025.

I tried to change my password but could not find an acct key, don't even remember having one! This is a new computer and it worked fine until I say that you are showing a very old picture for my account and showing I'm still on Windows 10!!! That is VERY OLD and I've used Firefox for years!!! I changed from Windows 10 to 11 on 7-1-25. Someone has hacked my account I guess!

What to do???

When I launch Firefox in Troubleshoot Mode and try to open the Settings page (about:preferences) right away, Firefox becomes unresponsive. This issue does not occur when Troubleshoot Mode is off.

I'm using Firefox 140.0.4 on macOS Sequoia 15.5.

I have had this problem on several websites, but most recently Xfinity. com. Pages in their rewards page have buttons to accept a reward. These buttons don't show up in firefox, but if I use chrome they appear and work properly

Dear Firefox Team,

I am writing to suggest a new feature that I believe would significantly enhance the user experience in Firefox.

Currently, when we encounter a PDF file on the web, Firefox only allows us to view or download it as a PDF. It would be incredibly beneficial if, when a user clicks on a PDF link (or during the download prompt), there was an option to choose whether to download the file as a PDF or as a JPG image.

This functionality would save users a considerable amount of time and effort by eliminating the need to use third-party online converters or desktop software to transform PDFs into JPGs. This is particularly useful for extracting images or specific pages from documents for quick sharing, presentations, or website use.

I believe this feature aligns with Firefox's commitment to user convenience and efficiency. Thank you for considering this suggestion."

Context: Here is an animation I generate with a program I'm developing. It being an SVG makes it useful to open in a web-browser. In chromium based browsers I have smooth animation, while in firefox I get much worse performance. At larger animations the problem becomes much more apparent. This is the approximately the largest animation that firefox can handle without lagging too much.

Expected: Firefox should have comparable SVG animation performance as chromium.

I have had a google account and a YouTube Channel ([email_1]@gmail.com) for decades. I recently added a new google email ([email_2]@gmail.com) and accustomed my old YouTube channel for [email_1]@gmail.com with the new email, [email_2]@gmail.com. On other browsers when I comment, the old YouTube account with the new email shows up as the commentor. Today, on my new Firefox browser.I discovered that the new email had created another YouTube channel which showed up as my ID for a comment on another YouTube channel. I deleted the new YouTube channel but, when I comment with the brand new Firefox browser, the old YouTube channel I deleted shows up. How can I correct that?

I was finally forced to update my Firefox to the released version. I am increasingly unable to log in to various "secure" websites with Firefox 140...1 although Chrome 106 (old, but can't update) has no problem. There are also a number of captchas that are simply invisible to firefox. Why is this happening?

Connectivity to www.xfinity.com disappeared...with latest firefox 140.0.4 as near as I can tell. xfinity still works on Google Chrome and Microsoft Edge. Please fix firefox browser so I don't have to go to chrome or edge. thanks!

Why is "Delete cookies and Site Data when Firefox is closed" checked and grayed out for me?

Everytime I open the FF browser I have to relog into everything, I didn't change any settings either, it just started doing this....

Hello... So, a couple of weeks ago, there was a 15-hour blackout during a Windows 11 update. I had exited firefox, and was shutting the laptop down, and it asked if I wanted to update and shut down (or other options). I chose update and close. When the lights came on and the router booted back up, Windows finished updating. It works, but here is the rub: whenever Ffox runs, a couple of minutes into the sessions, it will start displaying previous session screens, screen saver-like: one after the other every ten seconds or so. I can't X out, because it disappears whenever I move the cursor. The images appear not only on Ffox, but cover whatever other app's screen until I move the cursor, which is irritating when you're trying to meet the deadline on a novel! Please help! I am running version 140, by the way.

It has in the past. Now it all it comes up with a blank page.

This started today 16-July-25, when scrolling on a web page whenever I stop scrolling with either my finger or my Dell active pen Firefox brings up a window with the site's images with a view button. I don't recall changing any settings or preferences, any and all help is appreciated. Leonard R.
