Firefox Community Forum

Literally every single extensions I try to download says Installation aborted because the add-on appears to be corrupt. I don't know why because I just downloaded firefox.

Audio Equalizer and Amplifier(https://addons.mozilla.org/ru/firefox/addon/audio-equalizer-and-amplifier/) extension on Yandex Music(https://music.yandex.ru/) doesn't work, which was noticed only in Firefox. In other browsers, it worked correctly and without any problems, I don't understand what the problem is. PC rebooted, browser restarted, the extension uninstalled and installed again. How can this be fixed? The extension worked correctly in Chrome and Edge.

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 am a member of Nielsen Computer App. Why did Firefox quit allowing me to use/add this extension?? I guess if this is going to be a problem I will uninstall Firefox AGAIN and go with Chrome. I really like Firefox, but this is so upsetting that I cannot add the Nielsen Extension like before.

I'm trying to report a rogue version of this add-on, https://addons.mozilla.org/en-US/firefox/feedback/addon/%7B5c474add-03f0-4c67-9479-f32939d7599a%7D/. The actual add-on is fine and works well. Somehow a version, 1.5, got installed and I cannot keep it removed. Whenever I refresh FF, it shows back up. I cannot find any reference to this version on GitHub or on the extensions page. I have uninstalled FF and refreshed it. Nothing works. It keeps coming back. I also looked in the side-install directory, but there were no extensions there. If I remove the extension under the Add-ons Manager, it removes it and I can install it and it installs the correct version and it works until FF restarts and then the 1.5 version shows back up.

Several web sites say that they detect this ad block on my pc , but I can not find it through my pc sites. It seems to be kind of a worm that can not be disabled. I am using Firefox.

How can I open an ad on a one-time basis, as if there were an option when right-clicking?

Sometimes we search for something we want to buy. The ad is near the top of the search results and seems to be worth investigating.

But we can't open the ad. Our wonderful ad blocker is, like our guard dog, too zealous sometimes protecting us.

The answer I'm looking for is NOT to go into Settings, etc. That's swatting a fly with a sledge hammer.

When I click on the grey Last Pass icon, a "set preferences" screen is shown. The strictly necessary box is selected and I cannot change it. The Voluntary data collection box is clickable but does not make any difference if it is checked or unchecked. The screen is locked, no matter what I click or unclick. The only thing that I can do is to click the grey LP icon which closes the window.

On two other very similar computers, when the grey icon is clicked, I can search for passwords, alerts, account, etc. Why does the icon work on this computer. I've deleted the addin, deleted Firefox and reloaded several times.

Thank you

The issue with the sidebar AI robot's shortcut keys is that it will wake up the sidebar AI robot page by itself without opening my chat tool. Only when my chat tool is open, the shortcut key conflict with Firefox will not wake up the sidebar.
