Firefox Community Forum

Hi,

I have a question to the Firefox Snap permissions. I want to give Firefox the minimum of permissions which you can grant via Settings => Apps => Firefox Web Browser, because of security reasons.

So, a lot of them are self-explanatory, but there are some where I can’t imagine what that means and whether Firefox really needs such permission to run correctly and save or not. These are the following:

- Run in Background - Detect network devices using mDNS/DNS-SD - system-files - gsettings - Access hardware information - Mount-control - login-session-observe - opengl - system-packages-doc - Read/write access to U2F devices exposed - Access energy usage data

So, my question is: Does Firefox really need one of these above permissions to run correctly and save (I am asking because I don’t know if some of the above permissions are for security reasons activated) or can I turn them off?

Thank you!

Have an old computer and running Ubuntu

Want to keep Firefox but old man and don’t understand certain aspects

Could somebody email me a link that help? Is there such an animal?

Email to

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

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

I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

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?

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?

Hello everyone, i have Linux/Ubuntu software with Firefox browser and for 5 months it has not asked me to update, with it's pop up message. Now it is urgently asking me to update, i have followed the directions given in order to download the latest Firefox version as instructed but with no success. I am downloading it, but it doesn't have an instruction to "run" it. As a consequence, my system is getting slower and slower and i am afraid it will crush! Any ideas? Sooooos!!!

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

Subject: Assistance Required for Frequent Firefox Crashes on Ubuntu

Dear Developer Team,

I am facing persistent issues with Firefox crashing on my Ubuntu PC, and the problem has been ongoing for the past 40–50 days. Despite multiple attempts at troubleshooting—including uninstalling and reinstalling Firefox, clearing all caches, and other measures—the issue remains unresolved.

I’ve noticed that Firefox works for a few days after reinstallation, but then problems begin to surface, such as a half-screen display. Eventually, after restarting the PC, the browser starts crashing again.

Could you please investigate this matter urgently and provide a resolution? Additionally, I would appreciate it if you could clarify whether this might be related to a RAM issue or some other underlying cause.

Looking forward to your assistance.

Best regards, zimmi
