Lately I am getting emails from some corporations with nothing in the body. If I use a different browser I can read the e-mail. This only started about 2 weeks ago and so far only involves amazon.ca and mec.ca.

Both amazon.ca and mec.ca emails do not show anything in the body of an e-mail. If I use a different browser (duckduckgo) everything is ok and I can read the whole e-mail. This only started with the Firefox version 149 but is continuing with version 149.0.2. My email is handled by yahoo.ca via rogers.com. So far I am seeing this only with the two companies listed here. Any assistance is greatly appreciated.
