Firefox Community Forum

Buongiorno,

sto cercando di capire se il comportamento che sto osservando dipende da Firefox o da qualche impostazione relativa al ripristino della sessione.

Su una pagina che utilizza campi HTML input type="date" e input type="time", inserisco una data e un orario, ottengo correttamente il risultato e poi chiudo la scheda.

Dopo aver riaperto Firefox o ripristinato la sessione precedente, noto che in alcuni casi i valori visualizzati nei campi non corrispondono esattamente a quelli inseriti inizialmente oppure il risultato calcolato cambia leggermente.

Sono riuscito a riprodurre il comportamento su questa pagina dedicata al calcolo dell'ascendente ascendente.

Ho già provato a:

avviare Firefox in modalità risoluzione problemi; disattivare tutte le estensioni; cancellare cache e cookie; creare un nuovo profilo Firefox.

Su Chrome ed Edge non riesco a riprodurre lo stesso comportamento.

Qualcuno ha già riscontrato problemi simili con il ripristino automatico dei campi data/ora o con il recupero dello stato delle pagine dopo la riapertura del browser?

Grazie per qualsiasi suggerimento.

Is there another way to reopen my recently closed tabs which happened yesterday. When I hit the HISTORY button, the arrow I tried to open ( 'recently closed tabs' ) was not accessible (grey). Or did I accidentally hit a wrong button without noticing it, and how can I reverse it if I did? Thanks in advance.

I want to make the switch from Chrome to FF (to continue using UBO), and a problem I keep running into is media not displaying in Twitter(X)'s DMs while using Private Browsing mode. It only comes up as a gray block that says "Failed to Load" with "Retry" under it, but it never loads. It also asks that I re-enter my DM password every time the page reloads.

Everything works fine in a regular browser tab, the issues only occur in Private Browsing.

I have tried disabling UBO, disabling Enhanced Tracking Protection, and clicking the little shield icon in the URL and turning that off, too. Looking this up really didn't give me any results that actually helped, either.

Help would be much appreciated! This really is the last big hang-up I have to not switch.

Hello! I'm working on migrating a very old version of Firefox to a newer version, and the number one thing I want to make sure stays is the logins file(s). I went to export the CSV, and the `about:logins` page is blank! Despite this, both the key and logins files are populated, and the browser still autofills in each login as if it wasn't there. To mitigate this, I tried to export the .csv of all my logins, but it doesn't actually export. I'm not sure how to check action logs with Firefox, and I would like to grab the passwords, so I can migrate properly. Any advice would be appreciated. Thank you!

Здравствуйте. Я установил сертификаты по инструкции, которая лежит на s.sber.ru/70VQ2B . После этого в мозилле не прогружается полностью окно входа на online.sberbank.ru, не видно содержимого фреймов (сейчас попробую сделать скриншот). В Microsoft Edge работа нормальная. Удаление сертификатов, перезапуск браузера и компьютера не помогли. На других компьютерах ещё не проверял. Посоветуйте, пожалуйста, что можно сделать. Windows 10, Firefox 153.0.3 (64-разрядный).

I couldn't see password management page. To be specific, I click the "password" option in the top right corner lists. Normally it will show all the website that firefox saved, but now I couldn't see anything except frame. I will upload the interfance that I see. this problem happend since an update. And problem contines after several patches. The firefox version that I use is "153.0.3(64-bit)" please help!

High contrast setting only support 2 colors(unvisited links and visited links) as a consequence it does not support radio buttons(switches that move to left and right to turn on features). the buttons are invisible and waste hours of the users time.

Background: On August 6th morning EST after the August 5 2026 update, attempting to use firefox lead to the window with the "end process" button so I had to close the browser multiple times and then the next time I opened firefox, the bookmarks and history were wiped. I was able to restore using a backup saved on the computer and continue as normal (aside from losing some Cookie Clicker progress, reinstalling Tampermonkey userscripts, and redoing browser extension settings) but now there's an issue with trying to backup firefox data.

Issue: Trying to back up my firefox data leads to a "There was a problem backing up. Try again in a few minutes."

When going to about:config and typing browser.backup.backup-debug-info, I get {"lastBackupAttempt":1786243812,"errorCode":9,"lastRunStep":13}

When looking at Broswer Console, there is an entry saying BackupService: Could not create C:\Users\USERNAME\Documents\Restore Firefox\desktop.ini: NotAllowedError: Could not write to `C:\Users\USERNAME\Documents\Restore Firefox\desktop.ini': failed to open file for writing (NS_ERROR_FILE_ACCESS_DENIED) BackupService.sys.mjs:4116:23 but I don't know how to address that.

In this version of Firefox 152 for windows I'm currently unable to remove search related to google, ebay, perplexity and bing.

Please return possibility to remove those completely!

I don't want my browser to have anything to do with those listed above. I have had it removed in previous versions. Why did you add it to browser again?! Why don't you allow to remove it anymore?!

Racenet is a formguide put out by News Corp and subsribed to by mug punters like me but i am unable to download it with the message 403 ERROR the request could not be satisfiedbold text

Please help, it looks like my passwords are not synced anymore on any Mozilla I use. I sue a Mozilla portable at home and a classic desktop on my office. The synchronyzation works for bookmarks, browse history and download history but not a single password is imported on my sessions ! My files are present : see screenshot01 so my passwords are here. Login.json contains data. So what's the problem. The debug mode said that : see screenshot 02 Thanks for the help

After the last update, Firefox won't open. Instead, I get this message:

"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window."

I have closed it within the error message but the error message comes back each time I try to open Firefox.

Please help, Deb

Hello,

I'm troubleshooting a Firefox Desktop issue that I haven't been able to reproduce consistently in other browsers.

I use a browser-based precious metal calculator that performs calculations instantly using JavaScript. The page loads correctly, but after changing several input values and navigating between tabs, Firefox occasionally continues displaying an older calculated result until I perform a hard refresh (Ctrl + F5).

I've been able to reproduce the issue consistently using this scrap calculator scrap calculator. The page loads normally, but Firefox sometimes continues displaying an older calculated value until a hard refresh is performed.

The page itself loads normally, and there are no visible JavaScript errors in the Browser Console. However, the displayed value sometimes does not update immediately after changing the weight or purity inputs.

So far I have tested:

• Firefox Troubleshoot Mode
• Disabled all extensions
• Cleared cache and cookies
• Tested a new Firefox profile
• Disabled Enhanced Tracking Protection for the site

The issue appears only in Firefox Desktop. Chrome and Edge update the calculation instantly under the same conditions.

Has anyone encountered similar behavior involving JavaScript-driven calculations, form inputs, or page caching in Firefox?

Are there specific Firefox settings or diagnostic tools I should check to determine whether this is related to caching, page state restoration, or another browser feature?

Thank you for any guidance.

Has anyone reported this before? I am working as a contractor for a BigTech company. I am using an online platform/tool of theirs for several years now but after a recent update the work area doesn't show scroll bars anymore. That means I cannot scroll the editor window and can't go beyond the first page. This makes working (and earning money) almost impossible. As even for the tiniest edit I have to download huge tasks which is extremely time-consuming. An inquiry with my manager there indicated that other contractors on firefox experience the same issue. so they consider it a firefox compatibility issue of some kind. They gave me the advice to use Chrome, Edge or Safri instead. Well, I use firefox because I do not want to use Chrome/Edge... Don't know about Safari but my PC is on Windows... Any idea what can cause it and how to resolve the issue?
