Do you mean it is very slow to start, or very slow after starting?

[Tommaso (tommaso-trombetta)]

Yes, Firefox (76.0.1 64 bit, snap) startup is very slow (30sec).
After starting it, i navigate normally.

PC features:
-processor: Pentium(R) Dual-Core CPU T4300 @ 2.10GHz × 2
-memory: 4gb memory

Thank you,
Tom

[Olivier Tilloy (osomon)]

Could you please run the firefox snap from a terminal using the following command, and after it shows the window, close it and attach the corresponding output:

    snap run --trace-exec firefox

Thanks!

[Tommaso (tommaso-trombetta)]

Hi,

when i run the command, i get the following error:

~$: snap run --trace-exec firefox
error: cannot find current revision for snap firefox: readlink
/snap/firefox/current: no such file or directory

and fifefox doesn't start.

Sorry,
Tom

That's puzzling. And if you run "snap run firefox", the browser starts?

[Tommaso (tommaso-trombetta)]

No, always the same mistake:

tommi@tommi-pc:~$ snap run firefox
error: cannot find current revision for snap firefox: readlink
/snap/firefox/current: no such file or directory

I'm sorry,
Tom

So that's a different problem to the original one… Can you share the output of "snap info --abs-time firefox" ?

  **The new Firefox**

  Meet Firefox Quantum. Fast for good.

  Features:

  * A powerful, new engine that’s built for rapidfire performance.
  * Better, faster page loading that uses less computer memory.
  * Gorgeous design and smart features for intelligent browsing.

  **Now 2x faster**

  Crazy powerful browser engine? Check. Less time waiting around for pages
to
  load? Also, check. Firefox Quantum is twice as fast as Firefox was before.

  **Smooth browsing**

  Whether you’ve opened 10 or 1000, switching between tabs is faster than
  ever with Firefox’s new, responsive engine.

  **Seriously Private Browsing**

  The most powerful private browsing mode with added tracking protection.

  * Private Browsing
      * Firefox blocks online trackers while you browse and won’t remember
      your history after you’re done.

  * Tracking Protection

      * Some ads have hidden trackers that follow you online. Rude. We know.
      That’s why our powerful tool stops them cold.

  * Faster Page Loading

      * By blocking some ads and scripts that bog down browsing, pages load
      up to 44% faster. Now that’s a win-win.

  **Customization Features**

  * Extensions

  * Customize Firefox with thousands of extensions like LastPass, uBlock
  Origin, Evernote and more.

  * Themes

      * Make over Firefox to suit your mood! Choose a new look from our
theme
      categories or create your own.

  **Sync your devices**

  * Seamlessly access passwords, bookmarks and more. Plus, use our Send Tabs
  feature to instantly share open tabs between desktop, mobile and tablet.

  **Browse for good**

  Firefox is made by Mozilla, the non-profit champions of a healthy
internet.
  Mozilla also tackles issues like privacy, misinformation and trolling by
  investing in fellowships, campaigns and new technologies designed to make
  the internet healthier.

It appears the firefox snap is not installed on your system. Did you uninstall it since you reported the bug?

[Tommaso (tommaso-trombetta)]

sorry, but I was convinced that the version of firefox preinstalled on
ubuntu was SNAP!

No, it's not. So what you're saying in that the regular firefox package is very slow to start on your system. I'm updating the bug title to reflect that.

[Olivier Tilloy (osomon)]

Is startup equally slow if you start firefox in safe mode ("firefox -safe-mode") ?

[Tommaso (tommaso-trombetta)]

yes, it starts in 26sec

Could you please check whether starting firefox with a new profile takes equally long? Run:

    firefox -safe-mode -p

And create a new profile from there. Thanks!

[Tommaso (tommaso-trombetta)]

Yes, i created a new profile 'test', and it started in 30 sec.

firefox was updated to 77.0.1 since the bug was initially reported. Does the problem persist?

[Tommaso (tommaso-trombetta)]

start.
Thank you so much.
