I have been trying to update Thunderbird from V52 for a long time., Last time I tried, the add-ons I need were randomly only available for different versions, and hardly any of them were available for the latest version. After several days trawling through finding replacement add-ons trawling through hundreds of 20 per page lists and checking each add-on's versions history for compatibility , I gave up. Is there a simpler way to do this? There used to be pages of add ons for each version, no link for that anymore that I can see. Thunderbird would be a lot more popular if updates listed addons they made incompatible. Any ideas anyone?
