Firefox 社群討論區

I am trying to sync Firefox data to new computer. The Mozilla account only allows me to sync mobile devices. Online instructions do no match my version of Firefox 131.0.2, Ubuntu 24.04.

I just set up a server with linux Ubuntu 24.04 Desktop, with Firefox 129.0.2 included to do some dev and testing work.

Problem: Firefox seems unable to see or open files that are above or outside the user's home dir tree.

The only extra packages installed are the LAMP stack and Google Chrome, which has no problem. (had to have something for A/B testing.)

I've tried entering the url of file:///var/www/index.html, I've tried selecting 'open with...' from the files app, etc. Nothing works.

I can get to the file through http://localserver/index.html with no issues. I've verified permissions on the entire directory tree to the file. Everything from end to end has read permissions for all, 755.

I've checked the following advanced settings: security.sandbox.content.level..............................0 (started at 4, now at 0, no effect or change.) security.fileuri.strict_origin_policy.........................false (default setting as installed.)

I am able to open file:/// and get a dir listing. BUT, if I click on var, it gives "Access to the file was denied." I even tried changing the permissions on /var to 777, but no change.

This seems to be a Firefox only problem, since Google Chrome works where firefox doesn't.

I've spent several hours searching for ways to fix this, all with no success. Does anyone have any idea how to fix this, or even what to look at???

There is (IMHO) some missing functionality / unwanted feature or call it what you like (bug?).

History -> Manage History

select e.g. Last 7 days, right click on Name and select at least two attributes (you can choose from: Tags, Location,Most Recent Visit, Added and Last Modified)

Select the first entry of the list, all displayed fields are selected/highlighted.

Copy (either with the menu or with Ctrl-C) and paste it in your favourite text editor.

Why is only the URL copied? Other fields were also highlighted. Why are they not included?

This is WYSINWYG (what you see is not what you get).

It is possible to export bookmarks as an html file, so why is this not possible with history?

OK, it is possible to query the sqlite3 database directly to get some history info but it's a bit cumbersome.

To do so,

  copy the sqlite (places.sqlite) database to some safe place then open the database (with 'sqlite3 places.sqlite')
  get the history info you are interested in with a sqlite query,
  e.g. select title,visit_count,site_name,url,description,last_visit_date from moz_places where url like '%support%';

But there is no simple (AFAIK) way to convert 'last_visit_date' (an integer) to something human readable.

So either include the whole selection when something is copied (WYSIWYG) or provide export history as an html file.

ps: why is there on option 'other' in the list of 'topics' ? pps: I already posted this comment but it got lost somehow

Need an update for the update. My Mozilla settings say my operating system (Ubuntu 22.04) handles the updates, and it's a deadend. I can only use my browser for one minute before it freezes and a force quit is necessary.

Hi all. I have been using firefox with ubuntu 22.04 for about since when ubuntu 22.04 was released (2022).

On firefox, I usually use the nordpass and tab grouping extensions. For the third or fourth time in a row, firefox has simply vanished from my system from day to night.

I click the icon and nothing happens. I try typing "firefox" in the terminal and get

   Command '/usr/bin/firefox' requires the firefox snap to be installed.
   Please install it with:

   snap install firefox

Even if I accept the bizarreness of snap simply deciding from one day to another that I don't have this package (or did I never have it and never needed it in the first place?) and try "snap install firefox" I get:

   snap "firefox" is already installed, see 'snap help refresh'

After reading the result of "snap refresh help" I decided to "snap refresh" to update all of it's packages. Still, "snap install firefox" and "firefox" keep giving me the same result.

What is happening here?

Firefox 135.0 (64-bit) on Ubuntu 22.04.5. When trying to save any file (download, save image etc.) or trying to attach a file (in web-based gmail client or WhatsApp web client) nothing happens. Tried to refresh, switch off all extensions, clear download history - nothing helped. Chrome works on the same machine like a charm...

Do you have any suggestions?

Thank you

I use Firefox with DuckDuckGo on Ubuntu 24.04, Gnome desktop. My Firefox browser window regularly freezes but can be unfrozen by simply repositioning the window. This is really annoying.

I also use Chromium on the same system and there are no issues.

Any ideas?

Why cannot see Mozilla browser if I set it as a default browser?

Using Ubuntu: User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:134.0) Gecko/20100101 Firefox/134.0

Have to keep pressing keys periodically when streaming video in a Firefox tab to prevent the screen going dark. The Ubuntu Mate Power Management settings have all been configured to prevent the System from doing so, so I'm wondering if this has something to do with Firefox. As a caregiver for a disabled person otherwise without television access I would find this very helpful.

I would like to be able to view the names of tabs and the address bar. I am able to adjust the page views and all is well there. I do not want to use stronger glasses just to view the tabs and address bar and then switch to another strength of reading glasses.

Untill latest update when on a site was link, ex. http://site.site/repository/text.txt i could select the link and from context menu select "open link in new tab/window" or "save link as". Now only "copy link" action is available. Im on Ubuntu 24.04.3 LTS Thanks for any response.

This is one of the more annoying messages Firefox has recently added:

"Your browser is being managed by your organisation."

It is obviously wrong, because it is shown on a private Ubuntu 24.04 computer where I have myself installed Firefox from a tarball installation (Firefox version 142.0.1).

The about:policies page just shows: Homepage: URL "https://start.ubuntu-mate.org/"

  Locked	false
  StartPage	"homepage"

Why does Firefox give such obviously misleading information? All the other articles are not helpful at all either, some are talking about security software, some about malware.

This is an extremely user-unfriendly and confusing message: if security software is to blame, why does Firefox not tell what exactly is restricted? When malware changed something why does Firefox not tell what it changed? What even does the message actually imply, what is prevented what otherwise would work and why? What does the information shown on the about:policies page really tell me?

This is by the way shown when starting Firefox using an EMPTY directory for its profile (so making it use a brand new profile), running from a brand new installation directory extracted from a tar file. So what on earth makes it think it is "managed by my organization"?

There is no extension installed, no policies.json file in the newly created profile, nothing. It looks as if the firefox browser would just arrive with this weird setting/configuration comiled right into it?

I am experiencing an issue with the Picture-in-Picture (PiP) functionality in Firefox on Ubuntu. Unlike on Windows, where the PiP window automatically appears when switching tabs or pages, this does not happen on my system.

When I manually activate the PiP feature by clicking the button, the window does appear; however, it is placed behind the browser window and remains at the lowest level among other open windows. This causes it to be obscured by other applications and requires me to manually bring it to the front and adjust its position every time.

Is there a way to automate this process or resolve the issue so that the PiP window behaves as expected (i.e., stays on top of other windows and works seamlessly)? Please let me know if there are any settings, extensions, or workarounds that could address this problem.

Thank you in advance for your assistance!

I upgraded Firefox using Ubuntu's apt update, apt dist-upgrade. The upgrade process said my version is 134.0.1 but when I look on the Help button is says my version is 125.0.2. How do I upgrade to 134.0.1?

Here are the dpkg/apt logs for update:

2025-03-19 12:33:16 configure firefox:amd64 136.0.2~build1 <none> 2025-03-19 12:33:16 status unpacked firefox:amd64 136.0.2~build1 2025-03-19 12:33:16 status half-configured firefox:amd64 136.0.2~build1 2025-03-19 12:33:16 status installed firefox:amd64 136.0.2~build1

The problem is that when I tried opening gmail in my ubuntu, it is stuck at loading page, but other browsers like edge can open it without any problem (on the same system).

I tried every thing I can in the support forum of gmail/mozilla/others, but it's still stuck at loading.

That's all.
