Firefox コミュニティフォーラム

On my home screen, the visited sites are all crammed to one side, lower left, and all narrow in their appearance. I prefer they look as they did before, with the "tabs" or site boxes along the bottom of my regular sites. And I can't seem to "delete" the sites I visit; I can only dismiss them. And that often doesn't work as well either.

This has happened randomly on several different computers, both windows and ubuntu linux. It just now happened on my Win 11 computer. Was viewing the CNN news site and FF suddenly closed, without a "FF crashed..." message.When I clicked the icon to reopen it, it came up with the home page group of tabs instead of reopening the windows and tabs that were opened when it crashed. Worse, none of the previous months of history shows up and recently closed tabs and windows are both greyed out.

Is there a way of recovering the history of what I was working on at the time of the crash and what the hell is causing this? I am close to dumping FF and going with something else as this is highly annoying.

When I click on the star icon in the address bar the star icon is filled in, and existing bookmarks show with the filled-in star icon. But I no longer get a dropdown where I can edit, tag, or delete an existing bookmark, and URLs I click on don't show up in Recently Bookmarked so they haven't been added.

The places.sqlite file in my profile is not read-only, and I restarted Firefox (stupidly, before I took a screenshot of the pinned shortcuts on my new tabs page) and that made no difference.

Thanks in advance for any help!

I have about 19 jillion saved addresses in autofill. I know how to delete individual addresses, but I'd like to know if there's a way to select multiple entries or to delete all of them in a single operation.

I'm reposting a question already opened here because a moderator suggested to do so. Actually I though I was posting to the international forum from the URL...

I was trying to access a local HTTPS website of an embedded device (a Siemens S7-1500 PLC) that is using a self-signed certificate, but was unable to go on (attached image #1, in Italian language) due to the the SEC_ERROR_REUSED_ISSUER_AND_SERIAL error. I've browsed a similar PLC webserver in the past, so the fact that the device exposes a similar certificate serial number is not so strange for me, considering also it's self-signed.

The problem is that I cannot follow the instructions of the Mozilla knowledgebase here because I'm not able to identify the correct certificate of the website!

In the attached image #2 you can see that the connection is detected as not encrypted, I suppose because only the form part of the HTML that is posting the data using HTTPS while the rest is using HTTP, but I'm not sure. If I click on the padlock icon (attached image #3) the info about the current certificate is not displayed.

Then I went into Tools > Options and searched for "certificates"; as you can see in the attached images #4 and #5, neither in the Servers tab nor in the Authorities tab I can find any item that is related to 192.168.10.2 (the webserver IP address) or Siemens (the embedded device manufacturer). But unfortunately the error persist! Initially there was a 192.168.10.2:443 line in the Servers tab and I removed it and restarted Firefox, but it didn't solve, so at the moment the situation is the one depicted by the attachments.

I had to use Microsoft Edge to access the website, but I would like to solve this issue and use Firefox instead. Is there anything else I can do to bypass the error? Why doesn't the error page provide a way to correctly identify the wrong certificate using its fingerprint and/or name? Or, maybe, is there a way to disable this check for local IP addresses or for items in a whitelist?

Thanks for your help.

После недавнего обновления браузер перестал открывать сстраницы или открывает их очень медленно. Я очистил кеш, отключил производительность и ничего не помогает. Как решить это проблему? Пс. Хром работает отлично на этом же ПК.

Здравствуйте! При установке параметра "Настройки - Основные - Открывать Firefox автоматически при загрузке компьютера" в реестре создается запись HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run - Mozilla-Firefox-E385C0CFD98A494C: "путь-к-файлу\firefox.exe" -os-autostart Что за параметр командной строки -os-autostart? На на сайте поддержки Mozzila не нашел, ни интернет не подсказал. Я понимаю, что это автозапуск Firefox при запуске Windows. Но что конкретно делает данный параметр?

A radio station https://www.wfmt.com/schedule/ that has run successfully until today in Firefox no longer does, There is momentary blip of sound but then silence. It runs fine in Chrome. Another station continues to run successfully in Firefox

I am using Win 11, Microsoft Powertoys > Fancy Zones to manage the screen space on my 5120 x 1440 monitor. I also have System > Display > Multiple Displayers "Remember window locations based on monitor connection" enabled.

Any program I have besides FF will load up exactly where I had it last. FF shifts I am guessing 8 pixels to the right (or left, as this occurs if I close FF on the right side of the monitor.) If you look at the screenshots, the "opened at default" picture shows what FF looks like when I open it. You can see the xulstore.json file shows the screenX position is -8. If I manually type in 0, close out FF and reopen it, it will still shift back to the right a bit even with the .json still saying 0

How do I do one less thing when I turn the pc on and have FF open exactly as far left as possible instead of shifting over to the right?

In the menu for choosing which tab to add to a split view, tabs with the name/link of the original do not show up. I would like this fixed, although this is really only a minor inconvenience when duplicating a tab to put it into split view.

I can access Chewy with Safari, but not with Firefox. So the problem is not with my Mac settings and the problem is not with Chewy, the problem is with Firefox. Please address and fix it.

I noticed that some sites are showing up twice in the history when you go to history and look at the sites you've most recently been to. At first I assumed it was happening just with Youtube, but I have noticed it with other sites as well. This started happening a day or so ago. I recently updated to version 150.0.3, and I have no idea why it's happening. At first I thought it might be because I was signed into sync, but this hadn't happened on previous versions of Firefox and I've been signed into Sync for almost a year now and never saw this occur in that time. I even tried signing out of sync to see if that fixed the issue. it did not. I vaguely remember something like this happening on a much older version of the browser, but I dunno if you guys ever had a fix for it or not. I'm including a screenshot of the phenomenon for the sake of visual reference.

I Can't log in to my for Firefox on my new Linux Mint laptop. It's asking 2FA but I can't see it on my proton authenicator. My username and password are ok.

I recall setting up 2FA some years ago on Proton but don't recall ever using g it other than one. Can you please help?
