What operating system do you use? If you use Linux, you can simply download it from the main stable branch now I believe. Anyway, v115 is available to download right away from TB's main page.

Updates to 115 won't be offered from within TB until a number of bugs have been fixed, so as to provide a sufficiently stable basis for widespread deployment. That might be weeks or months from now. You can of course download 115 now from the TB website, but unless you are prepared to backup your current setup and revert to 102 if necessary, I wouldn't recommend it.

Best practice is to install 115 to a separate folder and run it in its own, new profile, keeping the current version separate and available to run on the existing profile.

Dude don't do it !!!!! I did and now things don't work right, not the worst mistake in my life but it's buggy & F'ed upped new software. I have a sinking feeling that the only way it will work properly is that you have to give up your prefered search engine I use Chrome with Duckduckgo for the links in the emails to connect to the internet. My proof is they also are pushing Mircosofts browser so I suspect they made some kind of deal with M$. They basically sold out their longtime users.

Are you typing nonsense in a vain hope of goading a reaction? This is not a chat forum where people talk a load of random gibber jabber or waste people's time.

But anyway doing the update over top of 102 made it buggy but I foolishly did a reinstall and now it is broke. I can download emails from my server but that is it, you can not link to sites which takes away like 70% of it's use.

I have already informed you to post your own question about your own issues to get help. Bothering other people is not helpful.
