Firefox コミュニティフォーラム

Sometimes I need to open XML files on my PC or in a network folder. If I open the file in the first tab in Firefox, it displays a neat and formatted rendering that makes it easier to read. However, if I open yet another tab, it displays a sequential text file that's difficult to read. How can I apply the style of the first tab to all open tabs? I've attached explanatory images (I hope). The second image shows how I'd like the XML file to always be displayed, regardless of the tab's position. Firefox 149.0.2 on windows 11

I received this email: Do you want to keep your Mozilla account and data?

I use Firefox every single day. I don't understand this message. Please explain.

Thank you, Cathy

Hello, I'm using Firefox 149.0.0 (current is 149.0.2) in France and started testing Mozilla VPN. According to the docs, Location should appear at the bottom of the VPN UI and you should be able to change this Location, what I'm interested in.

I have 'Paramètres' (Settings) instead of the Location/Country.

Is this specific to France ?

Thanks in advance & have a nice day, Marc.

To Firefox engineers and volunteers:

I am a native speaker of simplified Chinese, and I am currently running Firefox 149.0 for Windows desktop. There are some troubling issues and I hope to be able to fix them in the next version. Thank you very much.

The problem I encountered was that at least eight options, all in English, appeared in the browser's privacy and security settings, this has been in Simplified Chinese in previous versions of Firefox.

As a simplified Chinese user and English level of the user, I feel very inconvenient when using, I hope to get your response, thank you!

The original is simplified Chinese, I use the translator to translate into English, if there are mistakes please forgive me.

why not

For the past week everytime i use the search whether by using the address bar or context highlight a word i get a blank page as first result, if i search again i get the result. I use yahoo search engine as my main search engine for the past 10+ years. This doesnt happen if i set the google engine as i tested it in case it was an search engine issue.

I am using Firefox 149.0 (64-bit) with Yahoo.Com as my home page. All of a sudden, when I use the search bar at the top of the Yahoo Home Page, Firefox opens up a blank tab in response. Doesn't matter what I search for, same thing happens. Then, if I close that blank/empty tab and reattempt the same exact search again, it works fine.

This has been happening only for the past few days - was fine before. Is this Firefox? Or is this Yahoo? And how can I resolve the issue?

Thanks in advance.

As it says in the subject title. After performing a search and executing it. A new tab opens that displays about:blank. This occurs everytime an serach is performed the first time when opening Firefox. My current home page is set to Yahoo.com but will happen using any search engine.

When the tab is closed and the search is initiated again on the initial page. The search results populate. This is persistent and repeatable. This has happened since the previous update from the current version 149.0,2 on a Windows 11 pc.

The same thing happens on another pc that I use. And started happening without any prior glitches.

I have hased this question with no response since noticing the issue using the previous version.

Also. I have tried online suggestions to repair the issue with no positive results.

Needing a rapid fix.

I see many complaints about this new version v 149 for the Mac. The most outrageous one is that you can no longer drag links from a browser page (try BBC) to an email or a doc. You have to copy the link then it won't turn blue and only when received will it show up as a link. Like many others after 30 years use preferred over Safari and others I am seriously losing patience with Firefox. On the very day you announce split screen for Ff windows - you disable a vital feature that has worked for years causing me to waste so far 60 minutes of my hard pressed work time. Maybe this will be corrected in the next upgrade. But I am now intending to avoid all Firefox upgrades for 6 months after being offered. I doubt anyone on this forum will come back on this but my set-up is Mac OS Monterey - and Firefox v 148 worked perfectly before today. I hesitate to try and install the previous version because I am not used to doing such tech moves. Perhaps someone in the Mozilla head office congratulating themselves on the marvellous new upgrade will come across this but I doubt it

The Cache is never cleared after clearing, there are always about 9,3 MB left. According to my settings there should be 0 MB left. (When I check the Task Manager, Firefox ist always opened up to 10 times.) How can I make sure the Cache is completely cleared? I added Screenshots of both. Thnx for helping...

Firefox has exceeded all previous mess-ups by upgrading itself today (apparently sometime when my battery went flat and was then left recharging), and this happened despite my account being set for 'upgrades to be only installed manually'. Now every bookmark, all passwords and all the settings of my Home Page have been erased. I have no 'restore point' to resort to as supposedly all this info is synced to the cloud. But I can find no method to retrieve any of these files let alone one to restore them. This is a nightmare. Please help.
