Firefox コミュニティフォーラム

Dear Generous Help Volunteers,

I'm running Firefox 128.13.0 ESR (64-bit) on Windows 11 (Lenovo desktop).

If I use a Private Window, does that mean that "Containers" are redundant/not needed? If not, please explain in depth.

If I use a Private Window, does that mean that, while I have the browser open, any temporarily saved data can be accessed by any website? If so, could I use a Container, in a Private Window, only for those sites for which I need to keep cookie(s) (i.e. bank logins, shopping carts, etc.).

I noticed that SOME container extensions let you select to "Allow in Private Windows" and SOME do NOT. I noticed specifically that "Firefox Multi-Account Containers" will not let you select to "Allow in Private Windows", and my understanding is that this is required for ANY Containers to function. Is that correct? It's a bit confusing.

I have had some sites break using the standard browser (with Containers), that will often work if I use a Private Window. Often, all that seems broken is the "Captcha"; it just doesn't appear and the form will not complete without it. However, it works in a Private Window.

I'm a little confused about which does exactly what. I don't use Google or any social media sites and I don't want any of them to have access to any of my information.

I have also encountered an ongoing problem that is very frustrating and time-consuming: When I click a link in a webpage, 10 to 30 tabs will quickly open, instead of only one, and each has to be closed separately. This happens nearly all the time. Is there a solution to this?

With Appreciation & Kind Regards, Anne Fennell

The latest firefox update introduced tab groups, something I've been eagerly waiting for ever since chrome released it!

However, my firefox's tab groups don't hide the tabs correctly. In the video demo I see that when you click on the name of the tab group, it should collapse all the tabs and hide them.

In my firefox, when I click the tab group name, the tabs don't get hidden as expected.

Here is a video that shows the bug I'm referencing: https://imgur.com/a/8ewW1a2

I tried disabling all my extensions and restarting firefox, also tried in private mode, and it still was having the same experience.

Are there any about:config settings that I might have accidentally changed that could be causing this?

Thanks!

I signed up & paid for Mozilla Monitoring Premium. I get monthly reports from then, but when I click on "automatically delete data from brokers," I'm asked to sign up for Premium again. Please help.

When I read a thread and then it shows comments I can't read them on Mozilla anymore

I went to Google Chrome and I can read them so its something with my browser

I accidentally refreshed Firefox when I was having problems and didn't realize Refresh meant wiping everything clean. I found another thread about this, but it's 8 years old and things have changed. How do I use the "Old Firefox" folder on my desktop to restore all my bookmarks, history, etc.?

To replicate this issue, an image from my device is uploaded to a website that requires an image file input; the resulting image displayed on the website becomes corrupted and unreadable. The theory forming currently is the website is having issues retrieving or reading the input images; however, this bug seems to be consistent with several other websites, indicating Firefox is not able to read the images correctly and thus could result in fragmentation. - The image posted is a .png file of a screenshot of an attempt to post a picture to social media, based on the functionality of this bug, I am predicting this image will be fragmented and will only show blue and black lines. The image being posted online is also in a .png file format.

Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?

I used a number of extensions for years. I recently updated Firefox. Now, I don't see any of my previously installed extensions listed. What happened to them? Are they just "hiding" someplace or are they gone?

I've loved Firefox for years but can no longer use it because I have been unable to resolve this issue. All was well, an update was done, and bingo, I got this message. I don't know how to fix it. I removed Firefox from my desktop and re-installed. Same problem.

"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 cause this problem."

Hi, When connecting to a HTTP:// site, when you enter your username in the username field, Firefox prompts the user with: "This connection is not secure. Logins entered here could be compromised. Learn More".

How can I turn this message off?

We are running Firefox in kiosk mode in the browser (on a Windows 11 PC), and they are logging into an HTTP site using a touch screen, but when they click into the username box, they sometimes miss touch where to enter this username and instead touch the link mentioned in the message. This then takes them to the Mozilla homepage, but because it is running in kiosk mode, they are unable to navigate back, and they are prevented from closing and restarting Firefox. This is why we need to turn the message off.
