Where to download Firefox 26? My add-on doesn't work with 27.

I use Roboform, which isn't yet compatible with Firefox 27. I need to reinstall Firefox 26. Where can I download it from? Thanks.

Re: Where to download Firefox 26? My add-on doesn't work with 27.

Hello vsskanand,

The download worked fine and installed Firefox 26. During the install, I deselected 'Install Maintenance Service'. However, after I installed Firefox 26, I went to 'Help' > 'About' in order to just confirm that it was indeed 26. When I did that, Firefox automatically downloaded 27 and activated it on next start up.

So I had to uninstall 27 and reinstall 26 again. I just mention this for others who may go through the same thing. Once you install 26, if you go to 'Help' > 'About', Firefox will auto-upgrade to 27, even if you deselected 'Install Maintenance Service'.

Thanks for your help in getting me what I needed. I will close this problem.

Firefox 26 appeared to work fine but after I rebooted my PC, Firefox won't start up. I have to uninstall 26 and reinstall 27 in order to get Firefox to run. But then it's incompatible with RoboForm. I really don't want to switch browsers. Need help if anyone knows the resolution. Thanks.

@VSSKANAND Please do not post links outside of Mozilla sources. Previous versions of Firefox can be found at http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/ I have removed your link.

@sgracer The reason Firefox updates automatically again is because you haven't disabled it. Go to https://support.mozilla.org/en-US/kb/what-mozilla-maintenance-service to disable it. then report back to us.

Additionally, you may choose to contact Roboform at http://www.roboform.com/support to see if they plan to update Roboform to work with Firefox 27 as it is out of Mozilla's control.

Moses,

Which version of 26 should I download? There are about ten of them out there. Should I just go with the lastest one?

I did contact Roboform but they haven't responded yet.

Thanks.

The 26.0b1 to b10 were Beta builds of 26.0

.

Ideally you should use the latest Release due to security fixes. https://www.mozilla.org/security/known-vulnerabilities/firefox.html
