Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

no redirect but no extensions either hardly a real solution

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes). If the problem goes away, that tells us one thing. If it does not, that tells us something else.

It could be the work of one of your add-ons. Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.

What is your current home page setting?

You can check the browser.startup.homepage and startup.homepage* prefs on the about:config page.

A version from the repositories may behave differently then the version from the Mozilla server and you should probably contact Ubuntu for support about issues with their special branded version. Otherwise you can consider to install the version from the Mozilla server.

i found the solution it was in the .desktop file i removed %firefox% from the end of the command and it solved the issue.

That was very good work. Well done. Please flag your last post as Solved Problem so others will know.
